WebMar 17, 2024 · In the Contrastive Divergence algorithm, there are two phases: positive and negative. We’ll calculate the binary states of the hidden layers in the positive phase by computing the probabilities of weights and visible units. It is known as the positive phase since it enhances the likelihood of the training data set. metal gear solid coming back
