    Intel's Loihi roadmap calls for its brain chips to be as 'smart' as a mouse by 2019

    Intel said this week that a system based on its Loihi chip planned for 2019 will include the equivalent of 100 billion synapses, which is about the same brain complexity as a common mouse.

    Last September, Intel introduced the world to Loihi, a chip designed for what Intel calls probabilistic computing. Intel sees probabilistic computing as an important step on the road to artificial intelligence.

    Unlike a Core chip, which uses a sequential pipeline of instructions, Loihi is designed to mimic the way the brain works. The version of the Loihi chip that Intel introduced last year included 130,000 silicon “neurons” connected with 130 million “synapses,” the junctions that in humans connect the neurons within the brain.

    Google’s AI is learning to navigate like humans

    The company’s DeepMind artificial intelligence subsidiary has developed an AI that has learned how to navigate like a human being, the company announced in a blog post. Specifically, DeepMind’s AI has developed a system of spacial awareness that mimics human’s and other mammal’s grid cells–specific cells in the brain that allow for vector-based navigation, which allow us to calculate the direction and a distance to a location even if we’ve never traveled that route before. What’s most impressive about the AI’s mimicking of mammalian grid cells is that the AI did it on its own–it wasn’t programmed to mimic them.

      I also saw that Google was able to call out objects for people with visual impairments. I am particularly interested in this as it's something I've wanted for years. Maybe with the DeepMind navigation, it might eventually be able to help me get places. It's easy to get paranoid about all of this stuff, but we can't forget that it can genuinely help people too.

        Artificial intelligence has learned to probe the minds of other computers

        Anyone who’s had a frustrating interaction with Siri or Alexa knows that digital assistants just don’t get humans. What they need is what psychologists call theory of mind, an awareness of others’ beliefs and desires. Now, computer scientists have created an artificial intelligence (AI) that can probe the “minds” of other computers and predict their actions, the first step to fluid collaboration among machines—and between machines and people.

        “Theory of mind is clearly a crucial ability,” for navigating a world full of other minds says Alison Gopnik, a developmental psychologist at the University of California, Berkeley, who was not involved in the work. By about the age of 4, human children understand that the beliefs of another person may diverge from reality, and that those beliefs can be used to predict the person’s future behavior. Some of today’s computers can label facial expressions such as “happy” or “angry”—a skill associated with theory of mind—but they have little understanding of human emotions or what motivates us.

        The new project began as an attempt to get humans to understand computers. Many algorithms used by AI aren’t fully written by programmers, but instead rely on the machine “learning” as it sequentially tackles problems. The resulting computer-generated solutions are often black boxes, with algorithms too complex for human insight to penetrate. So Neil Rabinowitz, a research scientist at DeepMind in London, and colleagues created a theory of mind AI called “ToMnet” and had it observe other AIs to see what it could learn about how they work.

          That sound you hear is all the anti-AI pundits screaming. I think this is a really awesome development, but this sort of thing always freaks people out.
