loopy learning

[Brendan Frey]

It turns out that loopy propagation, or "turboinference", in Gaussian
networks can be used effectively for INFERENCE and LEARNING:

In this paper (submitted for publication in May), I show that 
iterative probability propagation in factor analysis networks has a fixed
point and I give an eigenvalue condition for global convergence.

I also show that iterative propagation can be used for learning factor
analyzer networks and give results on 

face recognition.
