NettetMaximum entropy distributions are those that are the “least informative” (i.e., have the greatest entropy) among a class of distributions with certain constraints. The principle of maximum entropy has roots across information theory, statistical mechanics, Bayesian probability, and philosophy. For this post, we’ll focus on the simple definition of … NettetWe therefore construct our a priori by taking the maximum entropy distribution checking the constraints imposed by the experts. Thus among the inﬁnite distributions that verify the constraints imposed by the experts, we choose the least informative distribution pmaxent, in other words the one closest to the conditional independence distribution.
