The library is now maintained by Tweag I/O. The main repo is now here.
A library for probabilistic programming in Haskell using probability monads. The emphasis is on composition of inference algorithms implemented in terms of monad transformers.
As of February 2020, we are working towards releasing monad-bayes on Hackage.
After the initial release, we will focus on improving documentation. In the
meantime, see the models folder for examples.
The basis for the code in this repository is the ICFP 2018 paper [2]. For the
code associated with the Haskell2015 paper [1], see the haskell2015
branch.
