I just came across the book Information, Physics and Computation, by Marc Mezard and Andrea Montanari, which was published just recently. The draft is still available as pdf files here. Now you know what I am currently reading.
And there is also this paper about
MAP estimation of Hidden Markov processes; I mention it as a follow-up to earlier posts.
"We reduce the MAP estimation to the energy minimization of an appropriately defined Ising spin model..." Sounds interesting.
