Mike, None of the Hawkin's papers I have read have given any results as impressive as the Hinton papers I cited. If you know of some that have, please send me references to the most impressive among them.
Hinton says he believe his system could scale efficiently to much larger nets. If that is true, a system having multiples of his modules would appear possibly able to learn how to handle a good chunk of sensory perception. Like, Ben I am not wed to a totally connectionist approach, but rather one that has attributes of both connectionist and symbolic approaches. I personally like to think in terms of systems where I have some idea what things represent, so I can think in terms of what I want them to do. But still I am impressed with what Hinton has shown, particularly if it can be made to scale well to much larger systems.

Hinton has shown how to automatically learn hierarchical neural nets that have 2000 hidden nodes in one layer, 500 in the next, and 1000 in the top layer Comment from a pal on Hinton who was similarly recommended on slashdot:(I'm ignorant here): "I also took a closer look at the Hinton stuff that the slashdot poster made reference to. To call this DBN stuff highly advanced over Hawkins is ridiculous. I looked at it already a couple of months ago. It took Hinton ***17-years*** - by his own admission - to figure out how to build a connectionist net that could reliably identify variations of handwritten numbers 1-9. And it's gonna take him about a MILLION more years to do general AI with this approach. Gakk. To me, the biggest problem with connectionist networks is all they ever solve are toy problems - and it's 20 years after connectionism become popular again." ------------------------------------------- agi Archives: http://www.listbox.com/member/archive/303/=now RSS Feed: http://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: http://www.listbox.com/member/?&; Powered by Listbox: http://www.listbox.com ------------------------------------------- agi Archives: http://www.listbox.com/member/archive/303/=now RSS Feed: http://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: http://www.listbox.com/member/?member_id=8660244&id_secret=106510220-47b225 Powered by Listbox: http://www.listbox.com
