    Hi all,

    Does anyone know how to learn some of the parameters in a DBN and freeze the rest of them - In case if I have those parameters a priori?

    For example in the HMM learning problem:

    X0 -> X1
      |          |
      v        v
    Y0     Y1

    , what if I already have the observation probability distribution P( Y | X ) and just need to learn the state transition probability function P ( X' | X ) from the evidences?

    Thanks,
    Hamed
