Abstract :
A new learning technique is introduced to solve the problem of the small and restrictive storage capacity of the Hopfield model. The technique exploits the maximum storage capacity. It fails only if appropriate weights do not exist to store the given set of patterns. The technique is not based on the concept of function minimization. Thus, there is no danger of getting stuck in local minima. The technique is free from the step size and moving target problems. Learning speed is very fast and depends on difficulties presented by the training patterns and not so much on the parameters of the algorithm. The technique is scalable. Its performance does not degrade as the problem size increases. An extensive analysis of the learning technique is provided through simulation results
