Hi Shu, I'm quite familiar with Jeff's work, am good friends with the director of RNI, and have seen talks/read papers on it. Not to burst any bubbles, but from everything I've seen it looks more like a marketing exercise than interesting science. Hawkins' work hasn't contributed to state of the art theoretical neuroscience at all (in fact, he's rehashed old ideas and tried to sell them through his company). What he has tried to sell as a 'new theory' is the (old) observeration that there is significant repetitive structure (cortical microcircuits) to cortex (which is less than half the neurons in the brain) and that thus there should be some general computational principles explaining cortical function. The 'theory' is a poor implementation of Bayesian inference in a network which has never demonstrated good pattern recognition on any standard benchmarks -- they have a few results on non-standard recognition problems, which aren't challenging as far as I can tell. I hope you don't take this as a reason not to send me links you think are cool -- please do! Just thought you might want another opinion on what you found :) best, .c Shu Wu wrote: > Found this talk (from TED 2003) very interesting: > http://www.ted.com/index.php/talks/view/id/125 > > "To date, there hasn't been an overarching theory of how the human brain > really works, Jeff Hawkins argues in this compelling talk.
