Learning of associative memory networks based upon cone-like domains of attraction

Abstract A learning algorithm for single layer perceptrons is proposed. First, a cone-like domain is derived such that all its elements can be recognized as a stored pattern in the perceptron network. The learning algorithm is obtained as a process that enlarges the cone-like domain. For autoassociative networks, it is shown that the cone-like domain becomes a domain of attraction for a stored pattern in the network. In this case, extended domains of attraction are also obtained by feeding the outputs of the network back to the input layer. In computer simulations, character recognition ability of the autoassociative network is examined.
