 K covariance variables.
 The mcRBM is parametrized by 5 variables:
 
- - `P`, a matrix (probably sparse) of pooling (F x K)
  - `U`, a matrix whose rows are visible covariance directions (I x F)
  - `W`, a matrix whose rows are visible mean directions (I x J)
  - `b`, a vector of hidden covariance biases (K)
