Hey guys, I don't think we've talked about it much, but Jeff Hawkins, founder of Palm, turned cognitive neuroscientist a few years ago, publishing "On Intelligence" and founding a company, Numenta, and the Redwood Neuroscience Institute (eventually renamed to Redwood Center for Theoretical Neuroscience), instantiated as a virtual institute in collaboration with UCB's HWNI. (Kind of like the Kavli Institute for Brain and Mind, locally.) He read a bunch of the neuroscience literature and, like Hecht-Nielsen, decided you don't need all of the brain to do biologically-inspired AI, just neocortex. He came up with a model he calls Hierarchical Temporal Memory, lucidly argued for in his book. After 18 months of hacking away at it, backed by a team of software developers and a research institute, he's recently decided to release the code as a "research release." If you find the time, check it out. Could provide us with some insight, especially where they seem to be stuck. (They haven't gotten predictive behavior yet.)
