Does the encoding of a restricted Boltzmann machine improve with more layers?

I'm using a Restricted Boltzmann Machine (RBM) as an autoencoder. For now, I use a simple architecture of two layers, the input (~100 nodes) and the output (3 nodes) layers. I'm thinking to add more ...

How do we calculate the hidden units values in a (Restricted) Boltzmann machine

The way I understand it is that hidden units are added to capture higher order interactions offering more capacity to the model. Now, the BM family are energy based undirected networks, meaning there'...

What is the role of the hidden vectors in restricted Boltzmann machines?

I'm learning about the restricted Boltzmann machine (RBM), and I just came up with two naive understandings of this model. But it seems these two understandings are so different. My first ...
