Revolution is changing that. You have warned me not to get too close. It does look a little bit hazardous. This robot dog hasnt been programmed to walk. Its learning by itself. Its called reinforcement learning. What weve done here is, weve given it this task to try to kind of stand up and move forward. When it does well, one of the Computer Scientists gives it the digital equivalent of a pat on the head. I can see its doing better and better. Its strong. I try and put that in its way, and its stronger than i am. Yeah. Have you trained it to make a beeline for me . Uhhuh. I feel like im battling the ai here, and the als winning. In just a few hours, its moving around by itself, even coping with the unexpected. Im really feeling an instinct to help it, but that is, of course, not good. You know, its learning, and maybe it looks a bit mean sometimes when we push it around, but, really, werejust trying to see what it can handle and help it learn new behaviours. This robot dog is the brain
We re looking for brain activity that s related to specific ideas or specific words that appear in the stories. so, for example, whenever you hear somebody talk about parking a car, there are certain patterns of activity in the brain that will be present that reliably correspond to that kind of idea. and we re trying to build up that mapping from this very large data set. the computer looks for patterns in the vast amounts of data from the scanner. with enough training, it can translate brain activity into words. to see how well it works, we picked a story for the lead scientist to listen to. recording: the war of the worlds. scream sound effects play headphones on, he went into the scanner. the martians in the pit had turned the heat ray on them a deep throbbing sound, a silver pencil of light, . and a narrow ribbon of bracken.
The heat ray on them a deep throbbing sound, a silver pencil of light, and a narrow ribbon of bracken. alexander huth: ..and grass and trees and houses - stretching as far as the eye could see was scorched. and this is the text the ai created from the brain scan. and the decoded version which misses a lot of things, but it gets some of the good stuff. fired the bullets out of the clip he had on him as he ran, and then i heard a huge crack as a large piece of concrete hit my forehead and then a giant ball of fire. the general idea of big noise got hurt is there in both of them. yeah. and then also the idea that something was on fire, the scorched versus a giant ball of fire . it captured all those things. but clearly not exactly the right words. so far, it can only analyse the brains of a handful of volunteers. but they hope it ll unlock the secrets of how our minds work. we are really pushing on, and a lot of our effort in the lab
