Associative-memory model based on neural networks: modification of Hopfield model
Sang-Hoon Oh, Tae‐Hoon Yoon, Jae Chang Kim · Optics Letters · 1988
The problem with the Hopfield associative-memory model caused by an imbalance between the number of ones and zeros in each stored vector is studied, and a modification of the Hopfield model that works well irrespective of the number of ones (or zeros) is proposed. This modified model can be implemented with no increase in memory.
