A categorical characterization of relative entropy on standard Borel spacesArticle

Authors: Nicolas Gagne ; Prakash Panangaden

    We give a categorical treatment, in the spirit of Baez and Fritz, of relative entropy for probability distributions defined on standard Borel spaces. We define a category suitable for reasoning about statistical inference on standard Borel spaces. We define relative entropy as a functor into Lawvere's category and we show convexity, lower semicontinuity and uniqueness.
