Ising Models with Hidden Markov Structure: Applications to Probabilistic Inference in Machine Learning

F. Herrera, U. A. Rozikov, M. V. Velasco

In this paper, we investigate tree-indexed Markov chains (Gibbs measures) defined by a Hamiltonian that couples two Ising layers: hidden spins \(s(x) \in \{\pm 1\}\) and observed s…
