Generative Models

Deep Boltzmann Machine

A Deep Boltzmann Machine (DBM) is a three-layer generative model. It is similar to a Deep Belief Network, but instead allows bidirectional connections in the bottom layers. Its energy function is as an extension of the energy function of the RBM:

$$ E\left(v, h\right) = -\sum^{i}_{i}v_{i}b_{i} - \sum^{N}_{n=1}\sum_{k}h_{n,k}b_{n,k}-\sum_{i, k}v_{i}w_{ik}h_{k} - \sum^{N-1}_{n=1}\sum_{k,l}h_{n,k}w_{n, k, l}h_{n+1, l}$$

for a DBM with $N$ hidden layers.
