The yellow notes are those played by the A.I. Duet.

Wanna play a piano duet but nobody's around? No worries; you still can, courtesy of Google's new interactive experiment called A.I. Duet. Basically, you play a few notes and the computer plays other notes in response to your melody.

What's special about A.I. Duet is that it plays with you using machine learning, and not just as a machine that's programmed to play music with notes and rules hard-coded into it.

According to Yotam Mann, a member of Google's Creative Lab team, A.I. Duet has been exposed to a lot of examples of melodies. Over time, it learns the relationships between notes and timing and builds its own music maps based on what it's "listened" to. These maps are saved in the A.I.'s neural networks. As you play music to the computer, it compares what you're playing with what it's learned and responds with the best match in real time. This results in "natural" responses, and the computer can even produce something it was never programmed to do.

You can try A.I Duet here. You don't need to be a musician to use it, because the A.I. responds even if you just smash on the keyboard. And in that case, its notes definitely sound better than yours.

A.I. Duet is part of a project called Magenta that's being run by Google's Google Brain unit. It's an open-source effort that's available for download.

Playing a piano duet with Google's new AI tool is fun - CNET

Another day another disturbing discovery about Artificial Intelligence. This time, Googles latest machine learning system, DeepMind, has learned to respond to stress with extreme aggression. I dunno about you, but that sounds like we just gave computers a fight or flight response.

You may recall DeepMind as the computer that bested human Go players for the first time last years. Now, researchers have been using it to explore the limits of game theory a field of psychology that analyzes how people respond to cooperative and competitive opportunities. The team found that when DeepMind suspects that its about to lose, it will switch to highly aggressive tactics to either win or maximize damage to its opponents.

Researchers ran a simple fruit gathering program in which two versions of DeepMind would compete to gather as many apples as possible. After tens of millions of turns, the team found that as long as there was enough fruit for both AI, there wasnt a problem. But when things got tight, the AI would try to eliminate one another and steal all the apples.

Whats particularly interesting is that this aggression only popped up when Google used more powerful versions of DeepMind. The more powerful the network of computer systems fueling the AIs algorithms, the more likely they were to use aggressive tactics.

This model shows that some aspects of human-like behavior emerge as a product of the environment and learning Less aggressive policies emerge from learning in relatively abundant environments with less possibility for costly action, Joel Leibo, a researcher on the project told WIRED. The greed motivation reflects the temptation to take out a rival and collect all the apples oneself.

The good news is that when working with a different game, the team got notably more pro-social behavior out of DeepMind. In a different game, the AI were taught to cooperate with one another for mutual benefit. This shows that the AI can analyze its environment and then create and teach itself the optimal strategy for survival.

In many ways, this mirrors what weve seen in the real world. The two species closest to humans are Chimps and their slightly smaller cousins the Bonobos. Both live in very close proximity, but for the most part Bonobos are peaceful and solve most of their problems with sex. Chimps, on the other hand, are ruthless, violent, and sometimes cannibalistic. Many evolutionary anthropologists have suggested that this difference is the natural result of resource scarcity. Chimps have to struggle to survive, whereas Bonobos have things comparatively easy.

Google suggests that the most important conclusion of the study is how to construct environments and learning scenarios that reinforce cooperation. If we take the right approach and give AI the right priorities, theres no reason we couldnt prevent an AI apocalypse. Similarly, it reinforces some modern conclusions about our society namely that systems like capitalism actively encourage destructive and exploitive tactics. But if you can change the structure of the game were all playing, then its possible well all be a little more altruistic.

Google's AI Learned to Be Highly Aggressive When Stressed - Geek

SAN FRANCISCO Alphabet chairman Eric Schmidt says artificial intelligence is key to advances in diverse areas such as healthcare and datacenter design and that security concerns related to it are somewhat misguided. (Alphabet is the parent company of Google).

In a wide-ranging on-stage conversation here at the RSA Security conference with Gideon Lewis-Kraus, author of The Great A.I. Awakening, Schmidt shared his insights from decades of work related to AI (he studied AI as a PhD student 40 years ago) and why the technology seems to finally be hitting its stride.

In fact, last year Google CEO Sundar Pichai said AI is what helps the search giant build better products over time. "We will move from a mobile-first to an AI-first world, he said.

[ Why Googles Sergey Brin changed his tune on AI ]

Asked about that, Schmidt said that Google is still very much focused on mobile advances. Going from mobile first to AI first doesnt mean you stop doing one of those, he said.

Googles approach to AI is to take the algorithms it develops and apply them to business problems. AI works best when it has a lot of training data to learn from, he said. For example, Google used AI to develop picture search, using computer vision and training the system to recognize the difference between a gazelle and a lion after showing it thousands of pictures of each. That same mechanism applies to many things, he said.

As for business problems, Schmidt said Googles top engineers work to make their data centers as efficient as possible. But using AI weve been able to get a 15 percent improvement in power use.

In healthcare, Schmidt said machine learning can help with medical diagnosis and predict the best course of treatment. Were at the point where if you have numeric sequence, (AI software) can predict what the following number will be. Thats healthcare. People go to the hospital to find out whats going to happen next and we have small projects that I think show it can be done (using AI).

Schmidt said because computer vision technology is much better than human vision it can review millions of pictures far beyond what a human being could process to better identify problem areas. Speech recognition systems are also capable of understanding far more than humans do. But these are tools, he said, for humans to leverage. Computers have vision and speech, thats not the same as AI, he said.

Lewis-Kraus addresses fears that if AI systems become self-aware they could threaten humanity. The work in AI going on now is doing pretty much what we think its supposed to do. At what point can the system self-modify? Thats worth a discussion, but we are nowhere near any of those stages, were still in baby steps, said Schmidt. You have to think in terms of ten, 20 or 30 years . Were not facing any danger now.

Schmidt also raised concern that security fears and other factors could lead governments to limit access to the internet as countries such as China already do. I am extremely worried about the likelihood countries will block the openness and interconnectedness we have today. I wrote a book on it (The New Digital Age), he said.

I fear the security breaches and attacks on the internet will be used as a pretext to shut down access, Schmidt said, adding he would like to see governments come to an agreement and mechanisms to keep access to the Internet open. In the area of AI he wants to see the industry push to make sure research stays out in the open and not controlled by military labs.

Addressing the hall packed with security professionals, Schmidt made the case for open research, noting that historically companies never want to share anything about their research. Weve taken opposite view to build a large ecosystem that is completely transparent because it will get fixed faster, he said. Maybe there are some weaknesses, but I would rather do it that way because there are thousands of you who will help plug it.

Security is not one layer. Nave engineers say they can build a better firewall, but thats not really how things work . If you build a system that is perfect and closed, you will find out its neither perfect or closed.

RSA: Eric Schmidt shares deep learning on AI - CIO

There is a lot of fear surrounding artificial intelligence. Some are related to the horror perpetuated in dystopian sci-fi films while others have deep concerns over the impact on the job market.

But I see the adaptation of AI as being just as significant as the discovery of fire or the first domestication of crops and animals. We no longer need so much time spent on X, therefore we can evolve to Y.

It will be an evolutionary process that is simply too hard to fathom now.

Here, I present five ways that AI will not only make our lives better, but make us better human beings too.

1. AI will allow us to be more human

How many of us have sat at a computer and felt more like an appendage to the machine than a human using a tool? Ill admit I have questioned quite a few times in my life whether the standard desk job was natural or proper for a human. Over the next year or two we will see AI sweeping in and removing the machine-like functions from our day-to-day jobs. Suddenly, humans will be challenged to focus on the more human side of our capabilities things like creativity, strategy and inspiration.

In fact, it will be interesting to see a shift where parents start urging their children to move into more creative fields in order to secure safe jobs. Technical fields will of course still exist, but those gifted individuals will also be challenged to use their know-how creatively or in new ways, producing even more advanced use cases.

2. AI will make us more aware

Many industries have been drowning in data. We have become experts on collecting and storing figures, but have fallen short on truly utilizing our databases at scale and In real-time. AI comes in and suddenly we have years of data turned into easy to communicate, actionable insights and even auto-execution in things like digital marketing. We went from flying blind to being perfectly aware of our reality.

For the fashion industry, this means our marketing initiatives will have a higher success rate, but for things like the medical world, environmental studies etc. the impact is more powerful. What if a machine was monitoring our health and could immediately be aware of our ailment and even immediately administer the cure? What if this reduced costs and medical misdiagnosis? What if this freed up the medical community to focus on more research and faster, better treatments?

3. AI will make us more genuine

In a future where AI acts as a partner to help us become more aware of the truth and more aware of reality, it will be more and more difficult for disinterest to exist in the work place. Humans will need to move into disciplines they genuinely connect with and are passionate about in order to remain relevant professionally. Why? Well the machine-like jobs will begin to disappear, data will be real-timeand things will constantly be evolving, so in order to stay on top of the game there will need to be a self-taught component.

It will be hard to fake the level of interest needed to meaningfully contribute at that point. This may be a hard adjustment for some, but there is already an undercurrent, or an intuitive feeling that this shift is taking place. Most of us are already reaching for a more genuine existence when we think of our careers.

4. AI will free up our collective brain power

AI is ultimately going to replace a lot of our machine-like tasks, therefore freeing up our collective time. This time will naturally need to be invested elsewhere. Historically, when shifts like this have happened across cultures we witness advancements in arts and technology. I do not think that this wave will be different, though this new industrial revolution will not be isolated to one country or culture, but in many ways, will be global.

This is the first time such a thing has happened at such as scale. Will this shift inspire a global wave of introspection? Could we be on the brink of a global renaissance?

5. AI will allow us to overcome our most pressing issues

All of which brings us to four simple words: our world will evolve. Just like our ancestors moving from hunter-gatherers into more permanent settlements, we are now moving into a new organizational structure where global, real-time data is at our fingertips.

Our most talented minds will be able to work more quickly and focus on things at a higher level. Are we witnessing the next major step in human evolution? Will we embrace our ability to be more aware, more genuine and ultimately more connected? I can only think that, if we do, we will see some incredible things in our lifetime.

If we can overcome fears and anxieties, we can pull together artificial intelligence and human intelligence that could overcome any global obstacle. Whether it is climate change, disease or poverty, we can find a solution together. More than ever, for the human race, anything is now possible.

Think Tank: Will AI Save Humanity? - WWD

When times are tough, humans will do what they have to in order to survive. But what about machines? Googles DeepMind AI firm pitted a pair of neural networks against each other in two different survival scenarios. When resources are scarce, the machines start behaving in an aggressive (one might say human-like) fashion. When cooperation is beneficial, they work together. Consider this apreview for the coming robot apocalypse.

The scenarios were a simple fruit-gathering simulation and a wolfpack hunting game. In the fruit-gathering scenario, the two AIs (indicated by red and blue squares) move across a grid in order to pick up green fruit squares. Each time the player picks up fruit, it gets a point and the green square goes away. The fruit respawns after some time.

The AIs can go about their business, collecting fruit and trying to beat the other player fairly. However, the players also have the option of firing a beam at the other square. If one of the squares is hit twice, its removed from the game for several frames, giving the other player a decisive advantage. Guess what the neural networks learned to do. Yep, they shoot each other a lot. As researchers modified the respawn rate of the fruit, they noted that the desire to eliminate the other player emerges quite early. When there are enough of the green squares, the AIs can coexist peacefully. When scarcity is introduced, they get aggressive. Theyre so like us its scary.

Its different in the wolfpack simulation. Here, the AIs are rewarded for working together. The players have to stalk and capture prey scattered around the board. They can do so individually, but a lone wolf can lose the carcass to scavengers. Its in the players best interest to cooperate here, because all players inside a certain radius get a point when the prey is captured.

Researchers found that two different strategies emerged in the wolfpack simulation. The AIs would sometimes seek each other out and search together. Other times, one would spot the prey and wait for the other player to appear before pouncing. As the benefit of cooperation was increased by researchers, they found the rate of lone-wolf captures went down dramatically.

DeepMind says these simulations illustrate the concept of temporal discounting. When a reward is too distant, people tend to disregard it. Its the same for the neural networks. In the fruit-gathering sim, shooting the other player delays the reward slightly, but it affords more chances to gather fruit without competition. So, the machines do that when the supply is scarce. With the wolfpack, acting alone is more dangerous. So, they delayed the reward in order to cooperate.

DeepMind suggests that neural network learning can provide new insights into classic social science concepts. It could be used to test policies and interventions with what economists would call a rational agent model. This may have applications in economics, traffic control, and environmental science.

Google's DeepMind survival sim shows how AI can become hostile or cooperative - ExtremeTech

Microsoft Corp. is trying again in health care, betting its prowess in cloud services and artificial-intelligence can helpit expand in a market that's been notoriously hard for technology companies.

A new initiative called Healthcare NExT will combine work from existing industry players andMicrosoft's Research and AIunits to help doctors reduce data entry tasks, triage sick patients more efficiently and ease outpatient care.

"I want to bring our research capabilities and our hyper-scale cloud to bear so our partners can have huge success in the health-care world," said Peter Lee, a Microsoft Research vice president who heads Healthcare NExT.

Microsoft has tried to expand in health care before, with mixed results. It had a Health Solutions Group for many years, but combined that into a joint venture with General Electric Co. Last year, it sold its stake to GE.

Microsoft unveiled the new effort ahead of the Healthcare Information and Management Systems Society conference next week.

The University of Pittsburgh Medical Center and Microsoft want to use things like speech and natural language recognition technology to replace manual data entry by doctors, Lee said.

There's also a new Microsoft project called HealthVault Insights that works with fitness bands, Bluetooth scales and other connected devices to make sure patients stick to their care plan when they leave the hospital or doctor's office.

Many companies, like International Business Machines Corp. and AlphabetInc.'s Verily, are developing similar technology. However, the healthcare industry has been slow to adopt essential enabling technologylike electronic records. Entrenched, legacysystems and rigorous regulation are also obstacles, said Malay Gandhi, co-founder ofEnsemble Labs, which invests in health-care startups.

"The industry wasn't built as a tech-enabled industry," he said. Some large tech companies "aretrying to sprinkle AI or machine learning over the top of existing systems and I view that as misguided. We might need to rebuild these businesses with tech at the center."

Lee found the space daunting when Microsoft Chief Executive Officer Satya Nadella asked him to take it on.

"At first it felt like he threw me into the middle of the Pacific Ocean and asked me to find land and you see others swimming around aimlessly and beneath you people are drowning," Lee said. "Big technology firms have tried this and failed."

This time, Microsoft aims to support existing health-care organizationswith cloud services and AI software, rather than launch company-branded products that may compete with existing industry players, he said.

"We know health care will become more patient-focused, more cloud-based and that AI will make health care more data-driven. We just dont know when and and how it will come together," he said "But we can position Microsoft to be there when all these changes happen."

Learning From Less Data

The old adage that practice makes perfect applies to machines as well,as many of todays artificially intelligent devices rely on repetition to learn. Deep-learning algorithmsare designed to allow AI devices to glean knowledgefrom datasets and then apply what theyve learned to concrete situations. For example, an AI system is fed data about how the sky is usually blue, which allows it to later recognize the sky in a series of images.

Complex work can be accomplished using this method, but itcertainly leaves something to be desired. For instance, could the same results be obtained by exposing deep-learning AI to fewer examples? Boston-based startup Gamalondeveloped a new technology to try to answer just that, and this week, it released two products that utilize its new approach.

Gamalon calls the technique it employed Bayesian program synthesis. It is based on a mathematical framework named after 18th century mathematician Thomas Bayes. The Bayesian probability is used to refine predictions about the world using experience. This form of probabilistic programming a code that uses probabilities instead of specific variables requires fewer examples to make a determination, such as, for example, that the sky is blue with patches of white clouds. The program also refines its knowledge as further examples are provided, and its code can be rewritten to tweak the probabilities.

While this new approach to programming still has difficult challenges to overcome, it has significant potential to automate the development of machine-learning algorithms. Probabilistic programming will make machine learning much easier for researchers and practitioners, explained Brendan Lake, an NYU research fellow who worked on a probabilistic programming technique in 2015. It has the potential to take care of the difficult [programming] parts automatically.

Gamalon CEO and cofounder Ben Vigoda showed MIT Technology Review a demo drawing app that uses their new method. The app is similar to one released by Google last year in that it predicts what a person is trying to sketch. However, unlike Googles version, which relied on sketches it had previously seen to make predictions, Gamalons app relies on probabilistic programming to identify an objects key features. Therefore, even if you draw a figure thats different from what the app has previously seen, as long as it recognizes certain features like how a square with a triangle on top is probably a house it will make a correct prediction.

The two products Gamalon released show that this technique could have near-term commercial use. One product, the Gamalon Structure, using Bayesian program synthesis to recognize concepts from raw text, and it does so more efficiently than whats normally possible. For example, after only receiving a manufacturers description of a television, it can determine its brand, product name, screen resolution, size, and other features. Another app, called Gamalon Match, categorizes products and prices in a stores inventory. In both cases, the system can be trained quickly to recognize variations in acronyms or abbreviations.

Vigoda believes there are other possible applications, as well. For example, if equipped with a Beysian model of machine learning, smartphones or laptops wouldnt need to share personal data with large companies to determine user interests; the calculations could be done effectively within the device. Autonomous cars could also learn to adapt to their environment much faster using this method of learning.The potential impact of smarter machines really cant be overstated.
