A child sees a ball, hears the word "ball", and associates them by Hebb's rule. <<<<<<<<<<<<<<<<<<<<<<< The hebb rule only explains how we associate patterns. It does not explain completely how we create pattern. If a child sees one ball it has many special features that are irrelevant for the abstract concept of "ball" i.e. connected matter which parts of the surface have a common distance r from a midpoint. Features like the colors on the ball, the reflexion of light, the value of r or the position of the ball's midpoint in space do not belong to the concept of a ball. Remember that we get 10000000 bits per second from the eyes. But a child extracts very soon from very few examples the right conception of a ball. And even if the ball is a relative simple object. It cannot be understood from seeing alone. The child has to move around the ball or has to move the ball to get the information. In a sense it must do some research to understand what a ball really is. So the hebb rule is surely important how we associate patterns. But I think it is only the tip of an iceberg. ------------------------------------------- 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=101455710-f059c4 Powered by Listbox: http://www.listbox.com
