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'...
