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

Now, Boltzmann machines are energy-based undirected networks, meaning there are no forward computations. Instead, for each input configuration $x$, a scalar energy is calculated to asses this ...

How is the distribution of the state related to the distribution of the units in Boltzmann machines?

I'm trying to understand Boltzmann machines. Tutorials explain it with two formulas. Logistic function for the probability of single units: $$p(unit=1)=\frac{1}{1+e^{-\sum_{x}wx } }$$ and, when the ...

How are Energy Based models really connected to Statistical Mechanics?

From statistical mechanics, the Boltzmann distribution over a system's energy states arises from the assumption that many replicas of the system are exchanging energy with each other. The ...

What are the differences between a deep belief network, a restricted Boltzmann machine and a deep Boltzmann machine?

Can anyone list the differences between deep Belief network (DBN), restricted Boltzmann machine (RBM), deep Boltzmann machine (DBM) using simple examples? Links to other resources are also ...
