Abstract: Generalized brain-state-in-a-box (GBSB) is one of the most known kind of Associative Memories. GBSB is based on a neural model, and needs an algorithm to perform the "training" operation that stores the patterns as equilibrium points of a system with a given state equation. Finding the optimum weight matrix to store a given set of patterns is the main objective of the training algorithm, and it can be seen as a classification problem. One of the most effective classification algorithms that we can find in literature is the Support Vector Machine (SVM). In this paper, we describe an algorithm that exploits capabilities of SVM to implement an efficient GBSB Associative Memory. Some properties of the networks designed in this way are evidenced, like a surprising generalized Hebb's law. The performance of the SVM approach is compared to existing methods with non-symmetric connections, by some design examples.
