Abstract

This is a mathematically oriented survey about the method of maximum entropy or minimum I-divergence, with a critical treatment of its various justifications and relation to Bayesian statistics. Information theoretic ideas are given substantial attention, including "information geometry". The axiomatic approach is considered as the best justification of maxent, as well as of alternate methods of minimizing some Bregman distance or f-divergence other than I-divergence. The possible interpretation of such alternate methods within the original maxent paradigm is also considered.
