WELCOME TO MY TECHNICAL UNIVERSE the physics of cognitive systems

I used to have a description of each of my papers on this page, but it got very boring to read as the numbers grew, so I moved most of it to here. After graduate work on the role of atomic and molecular chemistry in cosmic reionization, I have mainly focused my research on issues related to constraining cosmological models. A suite of papers developed methods for analyzing cosmological data sets and applied them to various CMB experiments and galaxy redshift surveys, often in collaboration with the experimentalists who had taken the data. Another series of papers tackled various “dirty laundry” issues such as microwave foregrounds and mass-to-light bias. Other papers like this one develop and apply techniques for clarifying the big picture in cosmology: comparing and combining diverse cosmological probes, cross-checking for consistency and constraining cosmological models and their free parameters. (The difference between cosmology and ice hockey is that I don’t get penalized for cross-checking…) My main current research interest is cosmology theory and phenomenology. I’m particularly enthusiastic about the prospects of comparing and combining current and upcoming data on CMB, LSS, galaxy clusters, lensing, LyA forest clustering, SN 1, 21 cm tomography, etc. to raise the ambition level beyond the current cosmological parameter game, testing rather than assuming the underlying physics. This paper contains my battle cry. I also retain a strong interest in low-level nuts-and-bolts analysis and interpretation of data, firmly believing that the devil is in the details, and am actively working on neutral hydrogen tomography theory, experiment and data analysis for our Omniscope project, which you can read all about here.

OTHER RESEARCH: SIDE INTERESTS Early galaxy formation and the end of the cosmic dark ages One of the main challenges in modern cosmology is to quantify how small density fluctuations at the recombination epoch at redshift around z=1000 evolved into the galaxies and the large-scale structure we observe in the universe today. My Ph.D. thesis with Joe Silk focused on ways of probing the interesting intermediate epoch. The emphasis was on the role played by non-linear feedback, where a small fraction of matter forming luminous objects such as stars or QSO’s can inject enough energy into their surrounding to radically alter subsequent events. We know that the intergalactic medium (IGM) was reionized at some point, but the details of when and how this occurred remain open. The absence of a Gunn-Peterson trough in the spectra of high-redshift quasars suggests that it happened before z=5, which could be achieved through supernova driven winds from early galaxies. Photoionization was thought to be able to partially reionize the IGM much earlier, perhaps early enough to affect the cosmic microwave background (CMB) fluctuations, especially in an open universe. However, extremely early reionization is ruled out by the COBE FIRAS constraints on the Compton y-distortion. To make predictions for when the first objects formed and how big they were, you need to worry about something I hate: molecules. Although I was so fed up with rate discrepancies in the molecule literature that I verged on making myself a Ghostbuster-style T-shirt reading “MOLECULES – JUST SAY NO”, the irony is that my molecule paper that I hated so much ended up being one of my most cited ones. Whereas others that I had lots of fun with went largely unnoticed…

Math problemsI’m also interested in physics-related mathematics problems in general. For instance, if you don’t believe that part of a constrained elliptic metal sheet may bend towards you if you try to push it away, you are making the same mistake that the famous mathematician Hadamard once did.

WELCOME TO MY TECHNICAL UNIVERSE I love working on projects that involve cool questions, great state-of-the-art data and powerful physical/mathematical/computational tools. During my first quarter-century as a physics researcher, this criterion has lead me to work mainly on cosmology and quantum information. Although I’m continuing my cosmology work with the HERA collaboration, the main focus of my current research is on the physics of cognitive systems: using physics-based techniques to understand how brains works and to build better AI (artificial intelligence) systems. If you’re interested in working with me on these topics, please let me know, as I’m potentially looking for new students and postdocs (see requirements). I’m fortunate to have collaborators who generously share amazing neuroscience data with my group, including Ed Boyden, Emery Brown and Tomaso Poggio at MIT and Gabriel Kreimann at Harvard, and to have such inspiring colleagues here in our MIT Physics Department in our new division studying the physics of living systems. I’ve been pleasantly surprised by how many data analysis techniques I’ve developed for cosmology can be adapted to neuroscience data as well. There’s clearly no shortage of fascinating questions surrounding the physics of intelligence, and there’s no shortage of powerful theoretical tools either, ranging from neural network physics and non-equilibrium statistical mechanics to information theory, the renormalization group and deep learning. Intriguingly and surprisingly, there’s a duality between the last two. I recently helped organize conferences on the physics of information and artificial intelligence. I’m very interested in the question of how to model an observer in physics, and if simple necessary conditions for a physical system being a conscious observer can help explain how the familiar object hierarchy of the classical world emerges from the raw mathematical formalism of quantum mechanics. Here’s a taxonomy of proposed consciousness measures. Here’s a TEDx-talk of mine about the physics of consciousness. Here’s an intriguing connection between critical behavior in magnets, language, music and DNA. In older work of mine on the physics of the brain, I showed that neuron decoherence is way too fast for the brain to be a quantum computer. However, it’s nonetheless interesting to study our brains as quantum systems, to better understand why they perceives the sort of classical world that they do. For example, why do we feel that we live in real space rather than Fourier space, even though both are equally valid quantum descriptions related by a unitary transformation?

Quantum information My work on the physics of cognitive systems is a natural outgrowth of my long-standing interest in quantum information, both for enabling new technologies such as quantum computing and for shedding new light on how the world fundamentally works. For example, I’m interested in how the second law of thermodynamics can be generalized to explain how the entropy of a system typically decreases while you observe a system and increases while you don’t, and how this can help explain how inflation causes the emergence of an arrow of time. When you don’t observe an interacting system, you can get decoherence, which I had the joy of rediscovering as a grad student – if you’d like to know more about what this is, check out my article in with John Archibald Wheeler in Scientific American here. I’m interested in decoherence both for its quantitative implications for quantum computing etc and for its philosophical implications for the interpretation of quantum mechanics. For much more on this wackier side of mine, click the banana icon above. Since macroscopic systems are virtually impossible to isolate from their surroundings, a number of quantitative predictions can be made for how their wavefunction will appear to collapse, in good agreement with what we in fact observe. Similar quantitative predictions can be made for models of heat baths, showing how the effects of the environment cause the familiar entropy increase and apparent directionality of time. Intriguingly, decoherence can also be shown to produce generalized coherent states, indicating that these are not merely a useful approximation, but indeed a type of quantum states that we should expect nature to be full of. All these changes in the quantum density matrix can in principle be measured experimentally, with phases and all.

Cosmology My cosmology research has been focused on precision cosmology, e.g., combining theoretical work with new measurements to place sharp constraints on cosmological models and their free parameters. (Skip to here if you already know all this.) Spectacular new measurements are providing powerful tools for this:

So far, I’ve worked mainly on CMB, LSS and 21 cm tomography, with some papers involving lensing, SN Ia and LyAF as well. Why do I find cosmology exciting?(Even if you don’t find cosmology exciting, there are good reasons why you should support physics research.)

  1. There are some very basic questions that still haven’t been answered. For instance,
    • Is really only 5% of our universe made of atoms? So it seems, but what precisely is the weird “dark matter” and “dark energy” that make up the rest?
    • Will the Universe expand forever or end in a cataclysmic crunch or big rip? The smart money is now on the first option, but the jury is still out.
    • How did it all begin, or did it? This is linked to particle physics and unifying gravity with quantum theory.
    • Are there infinitely many other stars, or does space connect back on itself? Most of my colleagues assume it is infinite and the data supports this, but we don’t know yet.
  2. Thanks to an avalanche of great new data, driven by advances in satellite, detector and computer technology, we may be only years away from answering some of these questions.

Satellites Rock! Since our atmosphere messes up most electromagnetic waves coming from space (the main exceptions being radio waves and visible light), the advent of satellites has revolutionized our ability to photograph the Universe in microwaves, infrared light, ultraviolet light, X-rays and gamma rays. New low-temperature detectors have greatly improved what can be done from the ground as well, and the the computer revolution has enabled us to gather and process huge data quantities, doing research that would have been unthinkable twenty years ago. This data avalanche has transformed cosmology from being a mainly theoretical field, occasionally ridiculed as speculative and flaky, into a data-driven quantitative field where competing theories can be tested with ever-increasing precision. I find CMB, LSS, lensing, SN Ia, LyAF, clusters and BBN to be very exciting areas, since they are all being transformed by new high-precision measurements as described below. Since each of them measures different but related aspects of the Universe, they both complement each other and allow lots of cross-checks. What are these cosmological parameters?Cosmic matter budget In our standard cosmological model, the Universe was once in an extremely dense and hot state, where things were essentially the same everywhere in space, with only tiny fluctuations (at the level of 0.00001) in the density. As the Universe expanded and cooled, gravitational instability caused these these fluctuations to grow into the galaxies and the large-scale structure that we observe in the Universe today. To calculate the details of this, we need to know about a dozen numbers, so-called cosmological parameters. Most of these parameters specify the cosmic matter budget, i.e., what the density of the Universe is made up of – the amounts of the following ingredients:

  • Baryons – the kind of particles that you and I and all the chemical elements we learned about in school are madeof : protons & neutrons. Baryons appear to make up only about 5% of all stuff in the Universe.
  • Photons – the particles that make uplight. Their density is the best measured one on this list.
  • Massive neutrinos – neutrinos are very shy particles. They are known to exist, and now at least two of the three or more kinds are known to have mass.
  • Cold dark matter – unseen mystery particles widely believed to exist. There seems to be about five times more of this strange stuff than baryons, making us a minority in the Universe.
  • Curvature – if the total density differs from a certain critical value, space will be curved. Sufficiently high density would make space be finite, curving back on itself like the 3D surface of a 4D hypersphere.
  • Dark energy – little more than a fancy name our ignorance of what seems to make up abouttwo thirdsof the matter budget. One popular candidates is a “Cosmological constant”, a.k.a. Lambda, which Einstein invented and then later called his greatest blunder. Other candidates are more complicated modifications toEinsteinstheory of Gravity as well as energy fields known as “quintessence”. Dark energy causes gravitational repulsion in place of attraction. Einstein invented it and called it his greatest mistake, but combining new SN Ia and CMB data indicates that we might be living with Lambda after all.

Then there are a few parameters describing those tiny fluctuations in the early Universe; exactly how tiny they were, the ratio of fluctuations on small and large scales, the relative phase of fluctuations in the different types of matter, etc. Accurately measuring these parameters would test the most popular theory for the origin of these wiggles, known as inflation, and teach us about physics at much higher energies than are accessible with particle accelerator experiments. Finally, there are a some parameters that Dick Bond, would refer to as “gastrophysics”, since they involve gas and other ghastly stuff. One example is the extent to which feedback from the first galaxies have affected the CMB fluctuations via reionization. Another example is bias, the relation between fluctuations in the matter density and the number of galaxies.One of my main current interests is using the avalanche of new data to raise the ambition level beyond cosmological parameters, testing rather than assuming the underlying physics. My battle cry is published here with nuts and bolts details here and here. The cosmic toolboxHere is a brief summary of some key cosmological observables and what they can teach us about cosmological parameters.

Photos of the cosmic microwave background (CMB) radiation like the one to the left show us the most distant object we can see: a hot, opaque wall of glowing hydrogen plasma about 14 billion light years away. Why is it there? Well, as we look further away, we’re seeing things that happened longer ago, since it’s taken the light a long time to get here. We see the Sun as it was eight minutes ago, the Andromeda galaxy the way it was a few million years ago and this glowing surface as it was just 400,000 years after the Big Bang. We can see that far back since the hydrogen gas that fills intergalactic space is transparent, but we can’t see further, since earlier the hydrogen was so hot that it was an ionized plasma, opaque to light, looking like a hot glowing wall just like the surface of the Sun. The detailed patterns of hotter and colder spots on this wall constitute a goldmine of information about the cosmological parameters mentioned above. If you are a newcomer and want an introduction to CMB fluctuations and what we can learn from them, I’ve written a review here. If you don’t have a physics background, I recommend the on-line tutorials by Wayne Hu and Ned Wright. Two new promising CMB fronts are opening up — CMB polarization and arcminute scale CMB, and are likely to keep the CMB field lively for at leastr another decade. Hydrogen tomography Mapping our universe in 3D by imaging the redshifted 21 cm line from neutral hydrogen has the potential to overtake the cosmic microwave background as our most powerful cosmological probe, because it can map a much larger volume of our Universe, shedding new light on the epoch of reionization, inflation, dark matter, dark energy, and neutrino masses. For this reason, my group built MITEoR, a pathfinder low-frequency radio interferometer whose goal was to test technologies that greatly reduce the cost of such 3D mapping for a given sensitivity. MITEoR accomplished this by using massive baseline redundancy both to enable automated precision calibration and to cut the correlator cost scaling from N2 to N log N, where N is the number of antennas. The success of MITEoR with its 64 dual-polarization elements bodes well for the more ambitious HERA project, which incorporates many of the technologies MITEoR tested using dramatically larger collecting area

.Galaxy cluster Large-scale structure: 3D mapping of the Universe with galaxy redshift surveys offers another window on dark matter properties, through its gravitational effects on galaxy clustering. This field is currently being transformed by everr larger Galaxy Redshift Survey. I’ve had lots of fun working with my colleagues on the Sloan Digital Sky Survey (SDSS) to carefully analyze the gargantuan galaxy maps and work out what they tell us about our cosmic composition, origins and ultimate fate. The abundance of galaxy clusters, the largest gravitationally bound and equilibrated blobs of stuff in the Universe, is a very sensitive probe of both the cosmic expansion history and the growth of matter clustering. Many powerful cluster finding techniques are contributing to rapid growth in the number of known clusters and our knowledge of their properties: identifying them in 3D galaxy surveys, seeing their hot gas as hot spots in X-ray maps or cold spots in microwave maps (the so-called SZ-effect) or spotting their gravitational effects with gravitational lensing.Gravitational lensing Yet another probe of dark matter is offered by gravitational lensing, whereby its gravitational pull bends light rays and distorts images of distant objects. The first large-scale detections of this effect were reported by four groups (astro-ph/0002500, 0003008, 0003014, 0003338) in the year 2000, and I anticipate making heavy use of such measurements as they continue to improve, partly in collaboration with Bhuvnesh Jain at Penn. Lensing is ultimately as promising as CMB and is free from the murky bias issues plaguing LSS and LyAF measurements, since it probes the matter density directly via its gravitational pull. I’ve also dabbled some in the stronger lensing effects caused by galaxy cores, which offer additional insights into the detailed nature of the dark matter.Supernovae Ia: Supernovae If a white dwarf (the corpse of a burned-out low-mass star like our Sun) orbits another dying star, it may gradually steal its gas and exceed the maximum mass with which it can be stable. This makes it collapse under its own weight and blow up in a cataclysmic explosion called a supernova of type Ia. Since all of these cosmic bombs weigh the same when they go off (about 1.4 solar masses, the so-called Chandrasekhar mass), they all release roughly the same amount of energy – and a more detailed calibration of this energy is possible by measuring how fast it dims, making it the best “standard candle” visible at cosmological distances. The supernova cosmology project and the high z SN search team mapped out how bright SN Ia looked at different redshifts found the first evidence in 1998 that the expansion of the Universe was accelerating. This approach can ultimately provide a direct measurement of the density of the Universe as a function of time, helping unravel the nature of dark energy – I hope the SNAP project or one of its competitores gets funded. The image to the left resulted from a different type of supernova, but I couldn’t resist showing it anyway..

.Lyman Alpha Forest The so-called Lyman Alpha Forest, cosmic gas clouds backlit by quasars, offers yet another new and exciting probe of how dark has clumped ordinary matter together, and is sensitive to an epoch when the Universe was merely 10-20% of its present age. Although relating the measured absorption to the densities of gas and dark matter involves some complications, it completely circumvents the Pandora’s of galaxy biasing. Cosmic observations are rapidly advancing on many other fronts as well, e.g., with direct measurements of the cosmic expansion rate and the cosmic baryon fraction.

Max Erik Tegmark[1] (born Max Shapiro[2][3] 5 May 1967) is a Swedish-American cosmologist. Tegmark is a professor at the Massachusetts Institute of Technology and the scientific director of the Foundational Questions Institute. He is also a co-founder of the Future of Life Institute, and has accepted donations from Elon Musk to investigate existential risk from advanced artificial intelligence.[4][5][6]


Early life[edit]

Tegmark was born in Sweden, the son of Karin Tegmark and American-born professor emeritus of mathematics Harold S. Shapiro. He graduated from the Royal Institute of Technology in Stockholm, Sweden and the Stockholm School of Economics and later received his PhD from the University of California, Berkeley. After having worked at the University of Pennsylvania, he is now at the Massachusetts Institute of Technology. While in high school, Tegmark and a friend created and sold a word processor written in pure machine code for the Swedish eight-bit computer ABC 80,[2] and a 3D Tetris-like game.[7]


His research has focused on cosmology, combining theoretical work with new measurements to place constraints on cosmological models and their free parameters, often in collaboration with experimentalists. He has over 200 publications, of which nine have been cited over 500 times.[8] He has developed data analysis tools based on information theory and applied them to cosmic microwave background experiments such as COBE, QMAP, and WMAP, and to galaxy redshift surveys such as the Las Campanas Redshift Survey, the 2dF Survey and the Sloan Digital Sky Survey.

With Daniel Eisenstein and Wayne Hu, he introduced the idea of using baryon acoustic oscillations as a standard ruler.[9][10] With Angelica de Oliveira-Costa and Andrew Hamilton, he discovered the anomalous multipole alignment in the WMAP data sometimes referred to as the “axis of evil”.[9][11] With Anthony Aguirre, he developed the cosmological interpretation of quantum mechanics.

Tegmark has also formulated the “Ultimate Ensemble theory of everything“, whose only postulate is that “all structures that exist mathematically exist also physically”. This simple theory, with no free parameters at all, suggests that in those structures complex enough to contain self-aware substructures (SASs), these SASs will subjectively perceive themselves as existing in a physically “real” world. This idea is formalized as the mathematical universe hypothesis,[12] described in his book Our Mathematical Universe.

Tegmark was elected Fellow of the American Physical Society in 2012 for, according to the citation, “his contributions to cosmology, including precision measurements from cosmic microwave background and galaxy clustering data, tests of inflation and gravitation theories, and the development of a new technology for low-frequency radio interferometry”.[13]

Personal life[edit]

He was married to astrophysicist Angelica de Oliveira-Costa in 1997, and divorced in 2009. They have two sons.[14] On August 5, 2012, Tegmark married Meia Chita, a Boston University Ph.D. candidate.[15][16]

Artificial intelligence

Artificial intelligence

Artificial intelligence (AI, also machine intelligence, MI) is intelligence exhibited by machines, rather than humans or other animals (natural intelligence, NI). In computer science, the field of AI research defines itself as the study of “intelligent agents”: any device that perceives its environment and takes actions that maximize its chance of success at some goal.[1] Colloquially, the term “artificial intelligence” is applied when a machine mimics “cognitive” functions that humans associate with other human minds, such as “learning” and “problem solving”.[2]

The scope of AI is disputed: as machines become increasingly capable, tasks considered as requiring “intelligence” are often removed from the definition, a phenomenon known as the AI effect, leading to the quip “AI is whatever hasn’t been done yet.”[3] For instance, optical character recognition is frequently excluded from “artificial intelligence”, having become a routine technology.[4] Capabilities generally classified as AI, as of 2017, include successfully understanding human speech,[5] competing at a high level in strategic game systems (such as chess and Go[6]), autonomous cars, intelligent routing in content delivery networks, military simulations, and interpreting complex data.

Artificial intelligence was founded as an academic discipline in 1956, and in the years since has experienced several waves of optimism,[7][8] followed by disappointment and the loss of funding (known as an “AI winter”),[9][10] followed by new approaches, success and renewed funding.[11] For most of its history, AI research has been divided into subfields that often fail to communicate with each other.[12] However, in the early 21st century statistical approaches to machine learning became successful enough to eclipse all other tools, approaches, problems and schools of thought.[11]

The traditional problems (or goals) of AI research include reasoning, knowledge, planning, learning, natural language processing, perception and the ability to move and manipulate objects.[13] General intelligence is among the field’s long-term goals.[14] Approaches include statistical methods, computational intelligence, and traditional symbolic AI. Many tools are used in AI, including versions of search and mathematical optimization, neural networks and methods based on statistics, probability and economics. The AI field draws upon computer science, mathematics, psychology, linguistics, philosophy, neuroscience, artificial psychology and many others.

The field was founded on the claim that human intelligence “can be so precisely described that a machine can be made to simulate it”.[15] This raises philosophical arguments about the nature of the mind and the ethics of creating artificial beings endowed with human-like intelligence, issues which have been explored by myth, fiction and philosophy since antiquity.[16] Some people also consider AI a danger to humanity if it progresses unabatedly.[17]

In the twenty-first century, AI techniques have experienced a resurgence following concurrent advances in computer power, large amounts of data, and theoretical understanding, and AI techniques have become an essential part of the technology industry, helping to solve many challenging problems in computer science.[18]

Superaccurate GPS Chips Coming to Smartphones in 2018

Broadcom has released the first mass-market GPS chips that use newer satellite signals to boost accuracy to 30 centimeters

Illustration: Miguel Navarro/Getty Images
We’ve all been there. You’re driving down the highway, just as Google Maps instructed, when Siri tells you to “proceed east for one-half mile, then merge onto the highway.” But you’re already on the highway. After a moment of confusion and perhaps some rude words about Siri and her extended AI family, you realize the problem: Your GPS isn’t accurate enough for your navigation app to tell if you’re on the highway or on the road beside it.

Those days are nearly at an end. At the ION GNSS+ conference in Portland, Ore., today Broadcom announced that it is sampling the first mass-market chip that can take advantage of a new breed of global navigation satellite signals and will give the next generation of smartphones 30-centimeter accuracy instead of today’s 5 meters. Even better, the chip works in a city’s concrete canyons, and it consumes half the power of today’s generation of chips. The chip, the BCM47755, has been included in the design of some smartphones slated for release in 2018, but Broadcom would not reveal which.

GPS and other global navigation satellite systems (GNSSs), such as Europe’s Galileo, Japan’s QZSS, and Russia’s Glonass, allow a receiver to determine its position by calculating its distance from three or more satellites. All GNSS satellites—even the oldest generation still in use—broadcast a message called the L1 signal, which includes the satellite’s location, the time, and an identifying signature pattern. A newer generation broadcasts a more complex signal called L5 at a different frequency in addition to the legacy L1 signal. The receiver essentially uses these signals to fix its distance from each satellite based on how long it takes the signal to go from satellite to receiver.

Broadcom’s receiver first locks onto the satellite with the L1 signal and then refines its calculated position with L5. The latter is superior, especially in cities, because it is much less prone to distortions from multipath reflections than L1.

In a city, the satellite’s signals reach the receiver both directly and by bouncing off of one or more buildings. The direct signal and any reflections arrive at slightly different times, and if they overlap, they add up to form a sort of signal blob. The receiver is looking for the peak of that blob to fix the time of arrival. But the messier the blob, the less accurate that fix, and the less accurate the final calculated position will be.

However, L5 signals are so brief that the reflections are unlikely to overlap with the direct signal. The receiver chip can simply ignore any signal after the first one it receives, which is the direct path. The Broadcom chip also uses information in the phase of the carrier signal to further improve accuracy.

Though there are advanced systems that use L5 on the market now, these are generally for industrial purposes, such as oil and gas exploration. Broadcom’s BCM47755 is the first mass-market chip that uses both L1 and L5.

Why is this only happening now? “Up to now there haven’t been enough L5 satellites in orbit,” says Manuel del Castillo, associate director of GNSS product marketing at Broadcom. At this point, there are about 30 such satellites in orbit, counting a set that only flies over Japan and Australia. Even in a city’s “narrow window of sky you can see six or seven, which is pretty good,” Del Castillo says. “So now is the right moment to launch.”

Broadcom had to get the improved accuracy to work within a smartphone’s limited power budget. Fundamentally, that came down to three things: moving to a more power-efficient 28-nanometer-chip manufacturing process, adopting a new radio architecture (which Broadcom would not disclose the details of), and designing a power-saving dual-core sensor hub. In total, they add up to a 50 percent power savings over Broadcom’s previous, less accurate chip. 

In smartphones, sensor hubs take the raw data from the system’s sensors and process it to provide only the information the phone’s applications processor needs, thereby taking the computational burden and its accompanying power draw off of the applications processor. For instance, a sensor hub might monitor the accelerometer looking for signs that you had flipped your phone’s orientation from vertical to horizontal. It would then just send the applications processor the equivalent of the word “horizontal” instead of a stream of complex accelerations.

The sensor hub in the BCM47755 takes advantage of the ARM’s “big.LITTLE” design—a dual-core architecture in which a simple low-power processor core is paired with a more complex core. The low-power core, in this case an ARM Cortex M-0, handles simple, continuous tasks. The more powerful but power-hungry core, a Cortex M-4, comes in only when it’s needed.

The BCM4775 is just the latest development in a global push for centimeter-level navigation accuracy. Bosch, Geo++, Mitsubishi Electric, and U-blox established a joint venture called Sapcorda Services in August, to provide centimeter-level accuracy. Sapcorda seems to depend on using ground stations to measure errors in GPS and Galileo satellite signals due to atmospheric distortions. Those measurements would then be sent to receivers in handsets and other systems to improve accuracy.

Japan’s US $1.9 billion Quasi-Zenith Satellite System (QZSS) also relies on error correction, but it additionally improves on urban navigation by adding a set of satellites that guarantees one is visible directly overhead even in the densest part of Tokyo. The third of those four satellites launched in August. A fourth is planned for October, and the system is to come online in 2018.

You have superpowers; cybernetic superpowers that allow you to do all kinds of things.

Think of it: at some time today you Googled a fact you really did not recognize, or your schedule reminded you to be someplace. A few days ago, I viewed a YouTube video clip on ways to connect a bowtie– while connecting my partner’s. I really felt kinda like Trinity. In all these circumstances, innovation is super powering my ability to do something better, quicker, or a lot more constantly compared to I otherwise could.

However somehow, none of these points occur when I claim, “You have superpowers.” Maybe it’s even more exact to claim, “You have superpowers, however do not feel superhuman.”

Superhumans control their powers with their body and minds. Take Superman for an example. I do not remember him pressing in a number of buttons prior to flying into the air. No. He simply leaped right into the air to begin flying. Jean Grey concentrates her mind and also items start relocating. They relocate their body or believe, similar to I do, however with superpowered results.

Unlike superhumans, our superpowers are consisted of in a mix lock box called a computer system. Often we know the combination, in some cases we just don’t and also wind up pushing buttons till something takes place. That’s why our cyber-superpowers feel much less than superhuman. They live outside of us and are no place near as easy to regulate as relocating your body or thinking. So making superhumans, we have to change the method we access our superpowers; we have to transform our human-machine user interface (HMI).

How We Got Right here

Our existing HMI, created in 1973 at Xerox PARC and also refined by Apple in the early 80s, is a whole lot like Descartes’ model of the mind-body partnership. The human (mind) demands and the computer system (body) acts. At the time, this design functioned excellent. Many interactions with computers were advanced calculation and language handling, jobs probably to be done seated at a desk or table with a key-board.

” Significantly obsolete user interfaces can not stay up to date with the expanding needs of technology.”

Yet because that time, we have begun taking our computer systems to all kinds of unexpected places: to the beach, in the auto, on an aircraft. Places we never ever imagine wanting to take a computer. And also as we do so, a speeding up quantity of product objects and also procedures have actually dematerialized right into package. Shops, songs, books, connections, flashlights, and thousands of more objects that at one time had their own distinctive interaction design are currently all consisted of inside a box with an HMI developed for resting at a table doing math as well as writing.

This just can not stay up to date with the expanding needs of technology. As well as it restricts our capacity to believe.

Our Interfaces Are Killing Our Capability to Believe

Today’s HMI counts greatly on our working memory. That’s your short-term, task-based memory, and also it keeps an eye on all the different action in a job, and also humans only have a lot. The even more we overload it, the much less useful it becomes. And anytime you disturb it, you shed 0.3 secs to Thirty Minutes in healing.

Allow me give you an example.

You’re resting on your sofa, as well as you’re a little chilly. You choose to go to your room to get a sweater. However the minute you go through the door to your space, you forget why you exist.

This isn’t really aging. It’s your brain being effective.

Your working memory was monitoring every little thing in the context of the sofa, but when you went through the doorway to your room, your brain claimed, “Oh! New context. Let me remove the functioning memory to be all set for this brand-new collection of tasks.” This is called an interrupt. The more we disrupt ourselves, the much less our brain could do due to the fact that it can not comply with a stream of consciousness.

Today’s HMI is a labyrinth of virtual doorways. Every single time we engage with it to transfer to the next task, we walk through a proverbial door, interrupting our working memory.

Do you know the amount of times you do this every day? A recent study uncovered that we communicate with our phone’s interface roughly 2,600 times a day. In a hr dealing with this post, I used the user interface to change between jobs 300 times. That does not consist of how many times social media tried to alert me of a brand-new blog post or comment. These constant disturbances maintain our mind so focused on shallow busy-ness, it battles to process deep or creative thought.

We are killing our capability to assume.

Think about one more cybernetic superpower: GPS. GPS is one of my favored cyber-superpowers. It tells me how you can arrive. It gets me around traffic congestion. It guides me on wonderful experiences.

However it’s much from ideal. Just like all our various other superpowers, GPS utilizes our current HMI. This implies I have to devote functioning memory to it and also continuously take notice of it. Although there is audio, the majority of instructions as well as demands appear on a fairly small screen with a salacious amount of information. This can just be read with heads-down emphasis and periodic looks at the real life to figure out the relationship between display as well as truth.

When you’re driving that’s an issue.

It’s crucial that you focus on reality when driving. Particularly when browsing a difficult or strange route, which is when GPS is most required as well as working memory is most tasked. The battle for functioning memory in these minutes threatens. And deadly. One mistake, one unforeseen alert from the gadget and lives can be lost.

Our user interfaces are actually eliminating us. Not super, computer systems. Not super.

HMI Has to Change

The means we access our superpowers has to transform. And now’s the moment. With a billion augmented truth devices hitting the industry in the following year, computing will certainly be released from the box.

This brand-new computing system is called “perceptual” or “cognitive computer.” Affective computing recognizes exactly what is occurring around it (and you) and acts appropriately. This will certainly trigger the dematerialization curve to substantially accelerate while we utilize technology in a lot more unforeseen areas. This implies modern technology will certainly be almost everywhere, and so will user interface.

If we remain to utilize our supercomputer HMI for this brand-new computing platform, our old as well as increasingly obsolete interfaces will get in between us and also the real life everywhere we look. The interruption sound will be deafening. So, unless we wish to end up being Matrix-like batteries, we have to move our HMI from supercomputer to superhuman.

You have superpowers; cybernetic superpowers that permit you to do all examples.

Think of it: at some time today you Googled a truth you really did not recognize, or your calendar advised you to be somewhere. The other day, I enjoyed a YouTube video clip on how you can connect a bowtie– while connecting my husband’s. I really felt kinda like Trinity. In all these situations, innovation is extremely powering my capability to do something better, faster, or much more consistently than I otherwise could.

Yet somehow, none of these things occur when I state, “You have superpowers.” Possibly it’s more accurate to state, “You have superpowers, but don’t feel superhuman.”

Superhumans manage their powers with their body and minds. Take Superman for an instance. I don’t remember him pressing in a bunch of switches prior to flying into the air. No. He simply leaped right into the air to start flying. Jean Grey focuses her mind and items start moving. They relocate their body or think, just like I do, yet with superpowered outcomes.

Unlike superhumans, our superpowers are had in a mix lock box called a computer. Sometimes we know the combination, often we just do not and end up pushing buttons till something occurs. That’s why our cyber-superpowers really feel much less compared to superhuman. They live outside of us and also are nowhere near as uncomplicated to control as relocating your body or thinking. So to earn superhumans, we should transform the method we access our superpowers; we need to transform our human-machine interface (HMI).

How We Obtained Here

Our current HMI, made in 1973 at Xerox PARC as well as improved by Apple in the early 80s, is a great deal like Descartes’ version of the mind-body connection. The human (mind) demands and also the computer (body) acts. At the time, this model worked excellent. Many interactions with computers were advanced computation and also language processing, jobs more than likely to be done seated at a workdesk or table with a key-board.

” Increasingly outdated interfaces can not stay up to date with the growing needs of modern technology.”

Yet since that time, we have begun taking our computer systems to all sort of unforeseen areas: to the coastline, in the auto, on a plane. Places we never imagine wishing to take a computer. And as we do so, an accelerating quantity of product things and also procedures have actually dematerialized right into package. Shops, music, books, relationships, flashlights, and thousands of even more objects that at one time had their very own distinctive interaction design are now all had inside a box with an HMI developed for resting at a table doing math as well as writing.

This just cannot stay on par with the growing needs of innovation. As well as it restricts our capability to think.

Our Interfaces Are Killing Our Capability to Think

Today’s HMI counts greatly on our working memory. That’s your temporary, task-based memory, and also it tracks all the various steps in a job, and also humans only have so much. The even more we overload it, the less useful it becomes. And also anytime you interrupt it, you lose 0.3 secs to Thirty Minutes in healing.

Let me offer you an instance.

You’re remaining on your couch, as well as you’re a little chilly. You decide to go to your room to get a sweater. However the minute you go through the door to your space, you neglect why you exist.

This isn’t really seniority. It’s your mind being effective.

Your working memory was keeping an eye on whatever in the context of the couch, yet when you went through the entrance to your bed room, your brain said, “Oh! New context. Let me clear the functioning memory to be ready for this brand-new set of tasks.” This is called an interrupt. The even more we disturb ourselves, the less our mind can do since it can not adhere to a train of thought.

Today’s HMI is a labyrinth of online doorways. Every time we connect with it to transfer to the following task, we go through a typical door, interrupting our functioning memory.

Do you know the number of times you do this everyday? A recent research uncovered that we engage with our phone’s interface about 2,600 times a day. In a hr dealing with this post, I utilized the interface to switch in between jobs 300 times. That does not include the number of times social networks attempted to inform me of a new post or comment. These consistent interruptions keep our mind so focused on superficial busy-ness, it struggles to refine deep or creative thought.

We are killing our capability to think.

Take into consideration another cybernetic superpower: GENERAL PRACTITIONERS. GENERAL PRACTITIONER is among my preferred cyber-superpowers. It tells me ways to arrive. It gets me around traffic congestion. It guides me on wonderful journeys.

Yet it’s far from ideal. Just like all our other superpowers, GPS utilizes our current HMI. This implies I need to dedicate working memory to it and also frequently focus on it. Although there is audio, a lot of instructions and needs appear on a reasonably little display with an obscene amount of data. This can just read with heads-down emphasis as well as periodic glimpses at the real life to determine the connection in between screen and reality.

When you’re driving that’s an issue.

It’s critical that you take note of fact when driving. Specifically when navigating a complex or unknown course, which is when GPS is most needed as well as functioning memory is most tasked. The battle for functioning memory in these moments threatens. And also harmful. One false move, one unexpected alert from the tool as well as lives can be shed.

Our interfaces are actually killing us. Not super, computer systems. Not incredibly.

HMI Has to Adjustment

The means we access our superpowers needs to change. And also now’s the moment. With a billion enhanced fact tools striking the market in the next year, computer will certainly be let loose from the box.

This new computing system is called “perceptual” or “cognitive computer.” Affective computer identifies what is taking place around it (and also you) and acts appropriately. This will cause the dematerialization curve to dramatically accelerate while we utilize technology in a lot more unanticipated locations. This indicates modern technology will certainly be almost everywhere, and so will user interface.

If we continuously utilize our supercomputer HMI for this brand-new computing system, our old as well as increasingly out-of-date interfaces will obtain between us as well as the real life everywhere we look. The disruption noise will be deafening. So, unless we wish to come to be Matrix-like batteries, we have to move our HMI from supercomputer to superhuman.

The Untapped Golden goose Of Just what is AI?/ Basic Concerns That Basically Nobody Knows About

Q. Just what is expert system?

A. It is the scientific research and engineering of making intelligent devices, specifically intelligent computer programs. It is related to the comparable task of utilizing computer systems to understand human intelligence, however AI does not have to restrict itself to approaches that are biologically observable.

Q. Yes, yet just what is intelligence?

A. Intelligence is the computational component of the ability to accomplish objectives worldwide. Diverse kinds as well as levels of intelligence happen in people, numerous pets as well as some makers.

Q. Isn’t really there a strong interpretation of intelligence that doesn’t depend on connecting it to human knowledge?

A. Not yet. The issue is that we could not yet define generally exactly what type of computational treatments we intend to call intelligent. We recognize some of the systems of intelligence and also not others.

Q. Is intelligence a single thing to make sure that one can ask an of course or no concern “Is this maker intelligent or not?”?

A. No. Intelligence involves devices, and also AI research study has actually uncovered how you can make computers accomplish a few of them and also not others. If doing a task requires just mechanisms that are well understood today, computer programs can offer really impressive efficiencies on these tasks. Such programs ought to be thought about “rather smart”.

Q. Isn’t AI about imitating human knowledge?

A. Often yet not constantly or perhaps normally. On the one hand, we can find out something about how to make devices address issues by observing other people or simply by observing our very own techniques. On the various other hand, most work in AI includes studying the problems the globe provides to knowledge instead of studying people or pets. AI researchers are cost-free to utilize approaches that are not observed in individuals or that involve a lot more computing than individuals can do.

Q. What concerning INTELLIGENCE? Do computer system programs have IQs?

A. No. INTELLIGENCE is based on the rates at which knowledge establishes in youngsters. It is the proportion of the age at which a youngster typically makes a certain rating to the child’s age. The range is included grownups in an ideal means. IQ associates well with various procedures of success or failure in life, however making computer systems that could rack up high up on INTELLIGENCE examinations would certainly be weakly associated with their usefulness. As an example, the ability of a youngster to repeat back a lengthy series of digits correlates well with other intellectual capacities, perhaps since it determines how much info the child can calculate with at the same time. Nonetheless, “digit period” is minor for even very restricted computer systems.

However, some of the troubles on IQ examinations are useful challenges for AI.

Q. What concerning various other comparisons between human and also computer intelligence?

Arthur R. Jensen [Jen98], a leading scientist in human knowledge, suggests “as a heuristic theory” that all regular human beings have the very same intellectual devices and that distinctions in knowledge are related to “quantitative biochemical and also physiological problems”. I see them as speed, short term memory, and also the capacity to form exact and retrievable long term memories.

Whether Jensen is appropriate about human knowledge, the situation in AI today is the opposite.

Computer programs have plenty of speed and also memory however their abilities represent the intellectual mechanisms that program designers recognize well enough to place in programs. Some abilities that kids usually don’t create till they are teens might remain in, as well as some capacities had by 2 years of age are still out. The matter is additionally complicated by the reality that the cognitive scientific researches still have actually not done well in establishing exactly just what the human abilities are. Very likely the organization of the intellectual systems for AI can usefully be different from that in people.

Whenever individuals do better compared to computers on some task or computer systems make use of a great deal of calculation to do in addition to individuals, this demonstrates that the program designers do not have understanding of the intellectual systems called for to do the job efficiently.

Q. When did AI research study begin?

A. After WWII, a variety of people individually began to deal with intelligent machines. The English mathematician Alan Turing could have been the very first. He gave a lecture on it in 1947. He also may have been the very first to determine that AI was finest looked into by shows computers as opposed to by building makers. By the late 1950s, there were lots of researchers on AI, and also most of them were basing their work with programs computers.

Q. Does AI purpose to put the human mind into the computer system?

A. Some researchers say they have that goal, however maybe they are utilizing the phrase metaphorically. The human mind has a great deal of peculiarities, and also I’m uncertain any individual is major regarding imitating all of them.

Q. What is the Turing test?

A. Alan Turing’s 1950 article Computing Machinery and also Knowledge [Tur50] reviewed problems for taking into consideration a device to be intelligent. He suggested that if the maker could effectively make believe to be human to a well-informed observer after that you definitely must consider it smart. This test would certainly satisfy lots of people yet not all thinkers. The viewer can connect with the device and a human by teletype (to prevent needing that the maker imitate the appearance or voice of the individual), and also the human would certainly aim to convince the observer that it was human and the machine would attempt to fool the viewer.

The Turing examination is a discriminatory examination. An equipment that passes the test needs to definitely be taken into consideration smart, however an equipment might still be taken into consideration smart without recognizing enough concerning humans to mimic a human.

Daniel Dennett’s book Brainchildren [Den98] has a superb discussion of the Turing test as well as the different partial Turing tests that have been carried out, i.e. with constraints on the onlooker’s understanding of AI and also the subject matter of wondering about. It ends up that some people are conveniently led into believing that a rather stupid program is intelligent.

Q. Does AI focus on human-level intelligence?

A. Yes. The ultimate initiative is to earn computer system programs that could address issues as well as achieve objectives in the world along with humans. Nevertheless, many people involved in certain study locations are much less enthusiastic.

Q. How far is AI from reaching human-level intelligence? When will it take place?

A. A couple of individuals think that human-level knowledge can be achieved by writing lots of programs of the kind people are currently creating as well as putting together vast knowledge bases of truths in the languages currently utilized for sharing knowledge.

Nevertheless, most AI scientists think that new basic ideas are needed, as well as a result it could not be predicted when human-level intelligence will certainly be achieved.

Q. Are computer systems the appropriate type of machine to be made smart?

A. Computer systems could be configured to simulate any type of device.

Lots of researchers designed non-computer makers, hoping that they would be intelligent in different ways than the computer programs might be. Nonetheless, they generally mimic their invented devices on a computer system and concern question that the brand-new maker deserves building. Since numerous billions of dollars that have actually been invested in making computer systems quicker and faster, another type of device would need to be extremely quickly to execute better compared to a program on a computer system replicating the maker.

Q. Are computers quick sufficient to be intelligent?

A. Some people believe much faster computer systems are required along with new ideas. My own opinion is that the computers of 30 years earlier were quickly sufficient if only we understood how to configure them. Obviously, rather apart from the ambitions of AI researchers, computers will certainly keep obtaining faster.

Q. What regarding parallel makers?

A. Equipments with lots of cpus are much faster than single processors could be. Similarity itself provides no benefits, as well as parallel devices are rather awkward to program. When extreme speed is needed, it is necessary to encounter this clumsiness.

Q. Exactly what about making a “child maker” that could boost by reading and also by gaining from experience?

A. This concept has actually been suggested many times, starting in the 1940s. Ultimately, it will certainly be made to work. However, AI programs haven’t yet gotten to the degree of being able to find out much of what a youngster learns from physical experience. Neither do present programs comprehend language all right to find out much by reading.

Q. Might an AI system be able to bootstrap itself to higher and also higher degree knowledge by considering AI?

A. I believe yes, yet we typically aren’t yet at a level of AI at which this process can start.

Q. Exactly what regarding chess?

A. Alexander Kronrod, a Russian AI researcher, said “Chess is the Drosophila of AI.” He was making an example with geneticists’ use of that fruit fly to examine inheritance. Playing chess needs certain intellectual mechanisms and also not others. Chess programs currently dip into grandmaster degree, yet they do it with limited intellectual devices as compared to those made use of by a human chess gamer, replacing big amounts of computation for understanding. When we understand these systems much better, we could construct human-level chess programs that do far much less computation compared to do present programs.

Unfortunately, the affordable as well as industrial aspects of making computer systems play chess have taken priority over making use of chess as a scientific domain. It is as if the geneticists after 1910 had actually arranged fruit fly races as well as focused their initiatives on breeding fruit flies that could win these races.

Q. Just what about Go?

A. The Chinese and also Japanese game of Go is additionally a parlor game where the gamers take turns removaling. Go exposes the weak point of our existing understanding of the intellectual mechanisms associated with human game having fun. Go programs are really bad gamers, despite substantial effort (not as much as for chess). The trouble appears to be that a setting in Go needs to be split psychologically right into a collection of subpositions which are first examined individually complied with by an analysis of their interaction. Humans use this in chess also, however chess programs consider the placement as a whole. Chess programs compensate for the absence of this intellectual system by doing thousands or, when it comes to Deep Blue, lots of countless times as much calculation.

Eventually, AI research study will certainly overcome this scandalous weak point.

Q. Do not some individuals say that AI is a bad concept?

A. The thinker John Searle claims that the suggestion of a non-biological machine being intelligent is mute. He proposes the Chinese space debate. The thinker Hubert Dreyfus claims that AI is difficult. The computer system scientist Joseph Weizenbaum claims the idea is obscene, anti-human as well as unethical. Numerous individuals have claimed that since artificial intelligence hasn’t already gotten to human degree now, it should be impossible. Still other individuals are disappointed that firms they bought declared bankruptcy.

Q. Typically aren’t computability concept and computational intricacy the tricks to AI? [Note to the layperson as well as beginners in computer science: These are rather technical branches of mathematical reasoning and computer science, and the answer to the inquiry has to be somewhat technical.]
A. No. These theories are relevant but do not attend to the basic problems of AI.

In the 1930s mathematical logicians, particularly Kurt Godel as well as Alan Turing, developed that there did not exist algorithms that were ensured to solve all troubles in certain important mathematical domains. Whether a sentence of very first order logic is a thesis is one example, as well as whether a polynomial formulas in a number of variables has integer services is another. Human beings resolve troubles in these domains at all times, and this has actually been offered as a debate (usually with some decors) that computer systems are fundamentally incapable of doing exactly what individuals do. Roger Penrose asserts this. Nonetheless, individuals can not assure to solve approximate problems in these domains either. See my Testimonial of The Emperor’s New Mind by Roger Penrose. A lot more essays as well as evaluations safeguarding AI study are in [McC96a]

In the 1960s computer scientists, particularly Steve Cook as well as Richard Karp created the theory of NP-complete issue domains. Troubles in these domains are understandable, but appear to take some time rapid in the dimension of the problem. Which sentences of propositional calculus are satisfiable is a standard example of an NP-complete issue domain name. People usually resolve problems in NP-complete domains in times much shorter compared to is guaranteed by the general formulas, however cannot solve them rapidly in general.

What is essential for AI is to have formulas as capable as people at solving troubles. The recognition of subdomains for which good algorithms exist is very important, however a great deal of AI issue solvers are not associated with readily recognized subdomains.

The concept of the trouble of general courses of problems is called computational intricacy. Thus far this theory hasn’t already interacted with AI as high as could have been really hoped. Success in problem solving by human beings and also by AI programs seems to depend on residential properties of troubles and also trouble resolving techniques that the neither the complexity scientists neither the AI neighborhood have had the ability to identify specifically.

Algorithmic intricacy theory as developed by Solomonoff, Kolmogorov as well as Chaitin (independently of each other) is additionally relevant. It specifies the complexity of a symbolic object as the size of the shortest program that will certainly create it. Showing that a prospect program is the fastest or close to the quickest is an unsolvable issue, yet representing items by short programs that generate them ought to often be illuminating even when you cannot prove that the program is the quickest.
