We consider the problem of neural association, which deals with the retrieval of a previously memorized pattern from its noisy version. The performance of various neural networks developed for this task may be judged in terms of their pattern retrieval capacities (the number of patterns that can be stored), and their error-correction (noise tolerance) capabilities. While significant progress has been made, most prior works in this area show poor performance with regard to pattern retrieval capacity and/or error correction. In this paper, we propose two new methods to significantly increase the pattern retrieval capacity of the Hopfield and Bidirectional Associative Memories (BAM). The main idea is to store patterns drawn from a family of low correlation sequences, similar to those used in Code Division Multiple Access (CDMA) communications, instead of storing purely random patterns as in prior works. These low correlation patterns can be obtained from random sequences by pre-coding the original sequences via simple operations that both real and artificial neurons are capable of accomplishing.
