摘要:

传统的两层二值双向联想记忆(BAM)网络因其结构的限制存在着存储容量有限、区分小差别模式和存储非正交模式能力不足的缺陷,结构上将其扩展至三层网络是一个有效的解决思路,但是三层二值BAM网络的学习是一个难题,而三层连续型BAM网络又存在处理二值问题不方便的问题。为了解决这些问题,提出一种三层结构的二值双向联想记忆网络,创新之处是采用了二值多层前向网络的MR Ⅱ算法实现了三层二值BAM网络的学习。实验结果表明,基于MR Ⅱ算法的三层二值BAM网络极大地提高了网络的存储容量和模式区分能力,同时保留了二值网络特定的优势,具有较高的理论与实用价值。

Abstract:

Because of the structural limitation of traditional two-layer binary bidirectional associative memory (BAM) network, there are some defects such as limited storage capacity, insufficiency to distinguish small differences in patterns, and lack of capacity to store non-orthogonal patterns. It is a solution that extending it to three-layer network. However, the learning of three-layer binary BAM network is a difficult problem, and three-layer continuous BMA network is inconvenient to deal with binary problems. In order to solve these problems, a three-layer binary BAM network is proposed. The network takes advantage of the MR Ⅱ learning algorithm for multilayer binary feedforward neural networks to perform the learning. The experimental results show that the three-layer binary BAM network based on MR Ⅱ algorithm can improve the storage capability effectively and retain the advantages of binary network, so it has relative high theoretical and practical values.
