To train the RBM, one has to obtain the positive and negative phase correlations. However, the computation of the latter is intractable. A way to approach it is via Gibbs sampling techniques (see Chapter 14). The fact that we know analytically the conditionals, P(hi|v) and P(vj|h), allows us to apply Gibbs sampling by sequentially drawing samples, that is,
