Another computational role for Hopfield nets
					Hidden units. Used to represent an interpretation of the inputs
	• Instead of using the net to store memories, use it to construct interpretations of sensory input. – The input is represented by the visible units. – The interpretation is represented by the states of the hidden units. – The badness of the interpretation is represented by the energy • This raises two difficult issues: – How do we escape from poor local minima to get good interpretations? – How do we learn the weights on connections to the hidden units?
