My current design maps nicely on a simplistic low-level structure of the brain: more or less static network with some long-reaching edges and some local edges, nodes of high degree, edges directed and with delay. My analysis suggests that it is a sufficient system to implement high-level capabilities associated with intelligence. In this model, nodes only need to perform unsupervised binary clustering (active/inactive), and rather simple online adaptive maximum margin with some tweaks seems to suffice. Maybe most of the brain is something like that, with high-level structure only used for optimization, encoding of inborn drives and bootstrapping. -- Vladimir Nesov [EMAIL PROTECTED] ------------------------------------------- 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=103754539-40ed26 Powered by Listbox: http://www.listbox.com
