Abstract

The associative net is a neural network model of associative memory that is unusual in having binary-valued connections between units. This net can work with high information efficiency, but only if the patterns to be stored are extremely sparse. In this paper we report how the efficiency of the net can be improved for more dense coding rates by using a partially-connected net. The information efficiency can be maintained at a high level over a 2–3 order of magnitude variation in the degree of pattern sparseness.
