WebThe Giry monad. #. Let X be a measurable space. The collection of all measures on X again forms a measurable space. This construction forms a monad on measurable spaces and measurable functions, called the Giry monad. Note that most sources use the term "Giry monad" for the restriction to probability measures. Here we include all measures …
WebJun 4, 2016 · The first question makes sense because both the distribution and the Giry monad are affine, and it seems that this property is typical for monads that are relevant in probability theory.
