Curious AI learns by exploring game worlds and making mistakes | New Scientist - 0 views

  •  
    "This type of approach can speed up learning times and improve the efficiency of algorithms, says Max Jaderberg at Google's AI company DeepMind. The company used a similar technique last year to teach an AI to explore a virtual maze. Its algorithm learned much more quickly than conventional reinforcement learning approaches. "Our agent is far quicker and requires a lot less experience from the world to train, making it much more data efficient," he says."

Google's AI Chief On Teaching Computers To Learn-And The Challenges Ahead - 0 views

    ""We'd have to show them 100,000 penny-farthings and tell them it's a bike," Giannandrea says. Then-looking on the bright side-he adds that "once they'd seen 100,000, they'd probably be better at identifying them than humans are.""

Google creates AI program that uses reasoning to navigate the London tube | Technology ... - 0 views

    "It is one of the first programs to combine an external memory with an approach called deep-learning, in which the program learns how to do tasks independently rather than being pre-programmed with a set of rules by a human."

Basic common sense is key to building more intelligent machines | New Scientist - 0 views

  •  
    "At Imperial College London, Murray Shanahan and colleagues are working on a way around this problem using an old, unfashionable technique called symbolic AI. "Basically this meant an engineer labelled everything for the AI," says Shanahan. His idea is to combine this with modern machine learning.

    Symbolic AI never took off, because manually describing everything quickly proved overwhelming. Modern AI has overcome that problem by using neural networks, which learn their own representations of the world around them. "They decide what is salient," says Marta Garnelo, also at Imperial College."

Google using romance novels to train its artificial intelligence to write fiction - 0 views

  •  
    "Google is using romance novels to teach its artificial intelligence (AI) system to better understand how people communicate.

    Researchers at Google Brain, the company's AI-focused deep learning project, presented a paper earlier this month that detailed techniques they used to teach its AI to write fiction - and the results were unexpectedly haunting."

Would you bet against sex robots? AI 'could leave half of world unemployed' | Technolog... - 0 views

    "Expert Moshe Vardi told the American Association for the Advancement of Science (AAAS): "We are approaching a time when machines will be able to outperform humans at almost any task.

    "I believe that society needs to confront this question before it is upon us: if machines are capable of doing almost any work humans can do, what will humans do?""

Big Data Ethics: racially biased training data versus machine learning / Boing Boing - 0 views

  •  
    "O'Neill recounts an exercise to improve service to homeless families in New York City, in which data-analysis was used to identify risk-factors for long-term homelessness. The problem, O'Neill describes, was that many of the factors in the existing data on homelessness were entangled with things like race (and its proxies, like ZIP codes, which map extensively to race in heavily segregated cities like New York). Using data that reflects racism in the system to train a machine-learning algorithm whose conclusions can't be readily understood runs the risk of embedding that racism in a new set of policies, these ones scrubbed clean of the appearance of bias with the application of objective-seeming mathematics.

Can Google's AlphaGo really feel it in its algorithms? | John Naughton | Opinion | The ... - 0 views

  •  
    "The really significant thing about AlphaGo is that it (and its creators) cannot explain its moves. And yet it plays a very difficult game expertly. So it's displaying a capability eerily similar to what we call intuition - "knowledge obtained without conscious reasoning". Up to now, we have regarded that as an exclusively human prerogative. It's what Newton was on about when he wrote "Hypotheses non fingo" in the second edition of his Principia: "I don't make hypotheses," he's saying, "I just know.""

    "What you may not realize, though, is that machine learning is already all around you, and it can exert a surprising degree of influence over your life. Don't believe me? You might be surprised."
