The Deep Mind of Demis Hassabis - "The big thing is what we call transfer learning. You've mastered one domain of things, how do you abstract that into something that's almost like a library of knowledge that you can now usefully apply in a new domain? That's the key to general knowledge. At the moment, we are good at processing perceptual information and then picking an action based on that. But when it goes to the next level, the concept level, nobody has been able to do that." (previously: 1,2) [more inside]
The simulated brain - "First computer model to produce complex behaviour performs almost as well as humans at simple number tasks." [1,2,3,4,5,etc.]
I've always been fascinated with the idea of having a photographic memory. They have products saying you can train yourself but I don't buy it. Can you really train your kid to have a photographic mind before age 6? I'm curious how many Mefites have snapshot memories.
Marijuana's effects on the brain are reversible "It appears that cognitive impairment from marijuana use is temporary and related to the amount of marijuana that has been recently smoked rather than permanent and related to an entire lifetime consumption." Hmm, I suppose it's good to know I can go back to being smart after being stupid for a little while.
