Marginal Polytope of a Deformed Exponential Family
Abstract
A deformed logarithm function called q-logarithm has received considerable attention by physicist after its introduction by C. Tsallis. J. Naudts has proposed a generalization called φ-logarithm and he has derived the basic properties of φ-exponential families. In this paper we study the related notion of marginal polytope in the case of a finite state space.
