Positive reinforcement

2016 became huge for improvements in synthetic intelligence and machine gaining knowledge.

But 2017 may additionally properly supply even more. Here are 5 key matters to stay up for.

Positive reinforcement

AlphaGo’s historical victory towards one of the excellent Go players of all time, Lee Sedol, became a landmark for the sphere of AI, and particularly for the approach called deep reinforcement mastering.

Reinforcement learning takes an idea from the methods that animals learn how positive behaviors have a tendency to bring about advantageous or poor final results. Using this approach, a laptop can say, determine out the way to navigate a maze with the aid of trial and errors and then accomplice the tremendous final results—exiting the maze—with the moves that led as much as it. This we could a machine study without practice or maybe express examples. The concept has been around for many years, but combining it with big (or deep) neural networks offers the strength had to make it paintings on truly complicated troubles (like the game of Go). Through relentless experimentation, as well as evaluation of previous games, AlphaGo found out for itself how to play the sport at a professional degree.

The hope is that reinforcement learning will now show beneficial in many actual-international conditions. And the latest launch of numerous simulated environments must spur progress at the necessary algorithms by means of growing the variety of abilities computer systems can accumulate this manner.

Dueling neural networks

At the banner AI academic accumulating held in Barcelona, the Neural Information Processing Systems conference, plenty of the excitement a new system getting to know technique called generative hostile networks.

Bitcoin could realistically be worth $500,000 by 2030

The first investor in Snapchat thinks bitcoin could realistically be worth $500,000 by 2030

Bitcoin has been the top-performing currency in the world in six of the past seven years, climbing from zero to a value of about $1,190.

But the cryptocurrency isn’t anywhere close to its potential, according to Jeremy Liew, the first investor in Snapchat, and Blockchain CEO and cofounder Peter Smith. In a presentation sent to Business Insider, the duo laid out their case for why it’s reasonable for bitcoin to explode to $500,000 by 2030.

Their argument is based on increased interest in bitcoin, thanks to:

Bitcoin-based remittances

Remittance transfers, or electronic money transfers to foreign countries, have almost doubled over the past 15 years to 0.76% of GDP, data from The World Bank shows.

“Expats sending money home have found in Bitcoin an inexpensive alternative, and we assume that the percentage of Bitcoin-based remittances will sharply increase with greater Bitcoin awareness,” the two say.


Liew and Smith said increased political uncertainty in the UK, US and in developing nations would help elevate the level of interest in bitcoin.

“We believe Bitcoin awareness, high liquidity, ease of transport and continued market outperformance as geopolitical risks mount, will make Bitcoin a strong contender for investment at a consumer and investor level,” the two said.

Mobile penetration

Liew and Smith believe the percentage of non-cash transactions will climb from 15% to 30% in the next 10 years as the world becomes more connected through smartphones. There’s only a 63% global smartphone penetration and the total number of smartphone users is expected to soar by 1 billion by 2020. GSMA,  a trade body that represents the interests of mobile operators worldwide, believes 90% of these users will come from developing countries.

This will make it possible for nearly everyone to have a bank in their pocket, and that should provide a boost for bitcoin as well. Liew and Smith say bitcoin could account for 50% of all of these transactions.

Here are the basic model drivers that Liew and Smith used:

  1. A bitcoin price of $1,000 in 2017.
  2. That network users will grow 61x from now until 2030. “Put another way, we need a population of bitcoin users around a quarter of the Chinese population (or 5% of the global population) in 2030 to see bitcoin at $500k,” Liew and Smith told Business Insider. Bitcoin’s user network grew from 120,000 users in 2013 to 6.5 million users in 2017, or about 54x, and this could be just the beginning. Growth of that magnitude would produce 400 million users in 2030.
  3. The average value of bitcoin held per user hits $25,000. “As institutional investor cash in Bitcoin, sophisticated investors trading Bitcoin, and Bitcoin-based ETFs proliferate, we think the average Bitcoin value held will increase to around $25k per Bitcoin holder,” Liew and Smith said. Currently, with a market cap of $16.4 billion, and 6.5 million user count, the average user holds $2,515 worth of bitcoin.
  4. Bitcoin’s 2030 market cap is decided by number of bitcoin holders multiplied by average bitcoin value held.
  5. Bitcoin’s 2030 supply will be about 20 million.
  6. Bitcoin’s 2030 price and user count total $500,000 and 400 million, respectively. The price is found by taking the $10 trillion market cap and dividing it by the fixed supply of 20 million bitcoin.

It’s important to note that a lot could go wrong, too. News surrounding bitcoin has been rather negative as of a late.

China, which is responsible for nearly 100% of trading in bitcoin, has been cracking down on trading. The three biggest exchanges recently announced a 0.2% fee on all transactions, in addition to blocking withdrawals from trading accounts.

Additionally, the US Securities and Exchange Commission rejected two bitcoin exchange-traded funds, and will make a ruling on another one in the future. It’s not expected to be approved. However, Smith thinks bitcoin is still in its early stages.

“The SEC’s ruling wasn’t a surprise to us,” he told Business Insider. “We know that getting this sort of approval is going to take (a potentially long) time,” Smith said. “In the meantime, bitcoin is already simple to buy and hold and, as the asset continues to mature, we’ll continue to see an increase in the development and deployment of surrounding products.”

BitcoinMarkets Insider

And while bitcoin hasn’t been granted regulatory approval here in the US, it is catching on elsewhere. On April 1, the cryptocurrency became a legal payment method in Japan.

Another threat to the future of the cryptocurrency is that developers are threatening to set up a “hard fork,” or alternative marketplace for bitcoin. This would result in the split of bitcoin into bitcoin and bitcoin unlimited. However, Smith says not to worry.

“Bitcoin has strong economic incentives to prevent this,” he said. “If the last two years of healthy contention and debate lead to a conclusion, it’s that Bitcoin is incredibly resilient and stable. In fact, the bitcoin Blockchain has operated for 7+ years with no downtime, a feat no other back-end system operating at this scale can claim.”

Anyone interested in bitcoin should also know that the cryptocurrency sees violent price swings that are uncommon among the more traditional currencies. Bitcoin rallied 20% in the first week of 2017 before crashing 35% on word China was cracking down on trading.

The cryptocurrency has regained those losses, and trades up about 25% so far this year.

These terrifying motion machines are the VR experience you’ve always wanted


These terrifying motion machines are the VR experience you’ve always wanted
by BRYAN CLARK — 18 hours ago in VIRTUAL REALITY
These terrifying motion machines are the VR experience you’ve always wanted

When paired together, the first gimmick (virtual reality), and the second gimmick (Robot VR or Gyro VR) could prove to be a potent combination.

What is it?
Ever been to a tech festival?
TNW Conference won best European Event 2016 for our festival vibe. See what’s in store for 2017.
Robot VR and Gyro VR are both machines designed to mimic the movement of what passengers are seeing in their VR headsets. If a roller coaster moves, you do too. If you’re flying a plane, the machines pitches and rolls as you do. If you’re piloting a robotic mech, well… you get the idea.

Both are motion machines, but each differ in how they achieve said motion.

Robot VR uses a massive robotic arm full of proprietary components to deliver both stability and flexibility. It’s best suited for “jerky” movements due to its ability to raise and drop its passengers, as needed. That said, it’s also capable of incredibly smooth movement when required. It also offers greater side-to-side movement potential than its counterpart, Gyro VR.

Gyro VR is better suited to experiences that involve spinning movement. Flying through space, driving a submarine, and the like are just some of what Gyro VR is capable of, although it was originally designed to be a sort of movie theater experience. Now, it’s a bit of a hybrid capable of a lot of really cool experiences.

Credit: Cnet
Neither has a distinct advantage, as each offers varying types of movement that could be better suited to the simulation you’re seeing at the time.

Why does it matter?
VR as an in-home technology is still a rather gimmicky experience. Most lack the PC horsepower to run powerful experiential simulations, and until 4k (or higher) resolution starts to grace each side of a VR headset it’s mostly a toy at this point. That’s not to say it isn’t a damn cool toy, but VR as a futuristic form of entertainment is, well, not there just yet.

What VR can do well is offer a way to experience movement in a whole new way. The carnival ride-type Gyro balls, and expensive movement machines open up entirely new worlds when paired with a VR headset.

That said, this definitely isn’t an at-home technology, but if you get the chance to try one at an event or theme park, it’s worth the price of admission. Over time, the technology will shrink to where something similar might find its way into an in-home market, although it’ll probably closer to the Virtuix Omni than the Robot VR or Gyro VR.

When is it coming?
Gyro VR is already here, although it’s limited to traveling demonstrations or theme park-like attractions with sizable purchasing power. Robot VR is still under construction, and should debut soon, but only in Korea (for now).

Twitter Training Same Country & Language Followers

Same Country & Language Followers

For those looking to grow a more focused following then targeting a country or language may be a logical place to start. There are ways to achieve this, but before you embark on this path there are a few things to keep in mind.

For the purpose of this guide I will refer to country and language targeting interchangeably as the same thing, or as targeting by geography. This is because they are both very broad in nature, and are achieved using similar methods of promotion.

Twitter is inherently open

Twitter was not built with country and language in mind. It is inherently open to allow anybody to follow anyone else. There is an option to make your account private, but to be honest that is counter-productive when you are trying to grow an audience. If you are looking to build a closed network of friends or acquaintances then Facebook and LinkedIn are probably better suited to the job. If you put your name up on a billboard then you will attract attention, potentially from people all over the world.

It may be unnecessary admin

Although you can focus your effort on certain geographies, it’s very hard to actually stop people from following you if they fall outside of them. You can block them if you want, but you may spend unnecessary hours doing this for very little gain. At the end of the day, unless you follow someone back they will not have any impact on your twitter profile or timeline.

Secondary benefits from ‘other’ followers

If you pick up some followers outside of your target geography then they may still provide some secondary benefits to you. They will increase your follower count, providing some small boost to your social proof, and they may retweet or like your tweets (an increase in engagement may improve the ranking of your tweets as twitter evolves it’s timeline algorithms). If they are connected to people in your target geography then they may end up passing your message on to them.

It makes sense if money is being spent

If you are using paid promotion such as twitter ads or twiends featured display, then it might make sense to use country targeting if your brand has this requirement. If you only sell your product or service into a certain market then you may want to make your promotion dollars go further by focusing on your target market.

The ‘spill over’ may be small

If you use the right type of promotion to target a geography then you should only collect a small number of ‘outside’ followers along the way – what I like to call ‘spill over’. My advice would be not to fret too much about this, unless the spill over becomes very large or time-consuming from an admin perspective.

How to target countries

Whether you are doing broad or targeted promotion, there are ways to focus on a country. The first two methods are probably the most effective due to the fact that they create a firm technical filter for that country. The other techniques will also work, but may have a slightly higher ‘spill over’ into non-desired countries.

  • Twitter ads allow you to choose countries when creating your ads, so regardless of any detailed targeting you select, your ads will only be shown to users in those countries.

    screenshot of twitter ads country targeting

  • Twiends allows you to choose up to 50 countries when you list yourself. Whether you use paid featured display or participate freely, your profile will only be shown to users in those countries.

    screenshot of twiends coutnry targeting

  • Contests can be focused by giving away prizes that can only be used in a certain country, and by announcing that only entrants from the target countries will be eligible.

    screenshot of Nissan India contest tweet

  • Outreach can be done using the location field that users provide, or the geo-location of their tweets. When searching for people to connect with use your target keyword and the ‘near:location’ operator. It’s not exact, but it will give you some quick easy wins, and you can move onto other 3rd party tools afterwards.

    screenshot of twitter location search

  • Material can be focused in-country. If you are creating content to attract followers you can craft it so that it only has local appeal.
  • Guest blogging can be focused towards publications that have a local audience.
  • Following back those that have followed you can be restricted to those that fall within your required area.

A note on accuracy

Platforms like twiends and twitter ads use IP geolocation data to place users. Although this is very accurate it is not without error occasionally. IP ranges are traded between internet service providers which can cause some users to be miss-classified periodically. But these cases are rare.

The location field used by users is also notoriously inaccurate and not standardized. Some people may say NYC, others New York City, and others Big Apple. You may need to use 3rd party tools when searching using this field. If you use the ‘near:location’ and ‘within:..mi’ search operators then these may only return results for user who are geo-tagging their tweets.

How to target languages

Unfortunately this is where it gets tricky. Language detection is a much harder mechanism for platforms to implement and they do have a higher margin of error. Systems may be able to detect a language accurately, but not be able to tell if it is someone’s first or second language. You can absolutely achieve good results here, but there will be some spill over to other language followers for some of these methods.

Outreach: Search filtering

When using outreach as a growth method you can use the twitter language operator to filter your searches for potential targets. As an example, if you were looking for french speaking people who used the word ‘blogging’ you would search for ‘blogging lang:fr’. Again, this is not a perfect system, but it will give you some good initial results. Move onto 3rd party tools when you need to do this at a larger scale.

screenshot of twitter search language filter

Twitter Ads

Twitter ads allow you to choose languages when targeting ad campaigns.

screenshot of twitter ads language filter

Country as proxy

A long established trick is to use country filtering as a proxy for language filtering. By carefully selecting a list of countries you can be reasonably certain that the majority of people will speak a certain language as either their first or second language.

For instance, if you wanted to target english you could choose the US, Canada, UK, Ireland, Australia, NZ, South Africa, etc. You could even extend that to parts of Europe and Africa, and be fairly confident that your new followers speak english. The same is easily done with spanish, german, french, arabic, etc. It’s all a matter of how much ‘spill over’ is acceptable to you.

map of country languages around the world

Language filtering usually only becomes an issue when you are doing broad promotion, such as on twiends. This is where you may be exposed to large numbers of new potential users in a short space of time. In this instance country filtering can be an effective solution.

When relying on other forms of promotion, such as contests, content and outreach, you will find that your efforts naturally attract same language followers, because the content you create will not be understood or of interest to foreign language speakers.

Putting it all together

If your brand or business is only relevant to certain countries and languages then by all means focus your efforts. Use the country and language filters available to you when using twiends and twitter ads, and focus your content and creatives on your target area.

Don’t lose too much sleep about spill over. If someone sends you a message in a foreign language then they have probably not looked at your profile and seen that you speak another language. That means they are probably relying on automation or may be spamming. Just block them and move on. For all the rest, they won’t do your account any harm…
