Inference in a DAG with replicated weights

etc.

h2

• The variables in h0 are conditionally independent given v0. – Inference is trivial. We just multiply v0 by – This is because the model above h0 implements a complementary prior. • Inference in the DAG is exactly equivalent to letting a Restricted Boltzmann Machine settle to equilibrium starting at the data.
