This is an implementation of Restricted Boltzmann Machine (RBMs). The following links are useful:

In the notebook, a abstract class called "Data Provider" provides a skeleton for any class that implements providing data batches to RBM. It is then used to feed MINST data to the RBM.
All the outputs at each training step are also shown.
