摘要: 对随机非对称连接Hopfield网络的突变行为进行理论研究. 结果表明, 在存储容量大于临界值的情况下, 网络的性能发生了一次新的突变; 在存储容量临界值邻域, 恢复带与伪稳定点带融合后又重新出现.

Abstract: The transition behavior of the properties of a Hopfield model with random asymmetric interactions was theoretically investigated. The results show that when the memory loading level is greater than its critical value, a new kind of transition of the networks occurs. The results also show that in the neighborhood of the critical point of the memory loading level, the retrieval band appears again after it has merged with the band composed of the spurious stable states.

Key words: associative memory, neural network, Hopfield model
