WebA classical model to describe this phenomenon is the Hopfield model [11], in which a recurrent neural network with N neurons is created with the p desired memories as fixed points of the dynamics. Specifically, the dynamics are given by (2) r t + 1 = φ J r t J = 1 N p S S T where φ is a threshold nonlinearity, and the connectivity J is an ... WebMar 29, 2024 · The Hopfield model has a long-standing tradition in statistical physics, being one of the few neural networks for which a theory is available. Extending the theory of Hopfield models for correlated data could help understand the success of deep neural networks, for instance describing how they extract features from data. ...
