Learning the Inverse Temperature of Ising Models under Hard Constraints using One Sample

Rohan Chauhan, Ioannis Panageas

We consider the problem of estimating inverse temperature parameter $β$ of an $n$ -dimensional truncated Ising model using a single sample. Given a graph $G = (V, E)$ with $n$ vertic…
