I referred to manually providing explanation in conversational format. Of course it's lossy, but whether it's lossy compared to the real world is not an issue, it's much more important how it compares to 'gist' scheme that we extract from full vision. It's clearly not much. Vision allows to attend to any of huge number of details present in the input, but there are only few details seen at a time. When a specific issue needs a spacial explanation, it can be carried out by explicitly specifying its structure in vector graphics. > > > Prewiring sensory input in a certain way merely pushes learning in > > certain direction, just like inbuilt drives bias action in theirs. > > Who said perception needs to be prewired?

Bad prewiring would consist in sticking signals from pixels on the retina to random parts of the brain, with random delays. It would take much more effort to acquire good visual perception in this case (and would be impossible on brain wetware). -- 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=98558129-0bdb63 Powered by Listbox: http://www.listbox.com
