Mike, This is a tutorial talk I saw recently (see Section A): http://nips.cc/Conferences/2007/Program/event.php?ID=577 Michael Lewicki Sensory Coding and Hierarchical Representations It describes how early stages of visual and auditory processing are optimally tuned to preserve information about outside world under biological and mechanical constraints. Retina owes its form to distortion of image from outside created by the eye before it reaches the retina. What we perceive is a reconstruction of outside world, and as such it much more obviously appears undistorted than image on the retina where you need to employ information theory to appreciate its undistortedness. -- 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=95818715-a78a9b Powered by Listbox: http://www.listbox.com
