Computing bounds for entropy of stationary Z^d Markov random fields
arXiv:1204.2612
Abstract
For any stationary $\mZ^d$-Gibbs measure that satisfies strong spatial mixing, we obtain sequences of upper and lower approximations that converge to its entropy. In the case, , these approximations are efficient in the sense that the approximations are accurate to within and can be computed in time polynomial in .
