Making Prediction in an Uncertain World
Environmental Structure and Cognitive Maps

This paper is extremely dense and we will read it over the course of two classes. For today read up to the section Visual Structure - Gateways. Much of the ground here should be pretty familiar. What is somewhat new is that we are going to start looking at larger structures. So far we have focussed almost exclusively on the active symbol. Starting today we will look at how active symbols fit together to form cognitive maps. The argument in the paper is that a key role of cognitive structure is for making effective predictions in the face of uncertainty. The mechanisms for doing this ought to look an awful lot like the mechanisms for building active symbols; the nature of the problem is the same, the temporal mechanics are just slightly different.
