Abstract

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.

标准Borel空间上相对熵的分类表征

在Baez和Fritz的精神下，我们给出了定义在标准Borel空间上的概率分布的相对熵的分类处理。我们定义了一个适合于在标准Borel空间上进行统计推理的范畴。我们将相对熵定义为Lawvere范畴的函子，并证明了它的凸性、下半连续性和唯一性。
