Description

dagger probabilistic programming library: tests

Published: 27 Mar 2022

README

dagger: a probabilistic programming library

The dagger library for probabilistic programming in OCaml. Currently implements:

  • Single-site Metropolis-Hastings, a.k.a. lightweight Metropolis-Hastings

  • Incrementalized single-site MH, similar to that implemented in Hakaru10

  • Sequential Monte-Carlo, with systematic and stratified resampling

The main package is prbnmcn-dagger. Packages prbnmcn-dagger-gsl and prbnmcn-dagger-stats provide distributions implemented respectively through the GSL (GPL-licensed) and prbnmcn-stats (MIT-licensed).

Look no further for the documentation.

Examples will be made available in the examples subdirectory. For now, you'll find:

  • an implementation of a 2d ising model and a toy study of its behaviour around its critical temperature

  • an experiment on forecasting wind power production using an ad-hoc Kalman filter

Contributing

Contributions and issue reports are welcome. Development currently happen on https://gitlab.com/igarnier/monorepo/ but I can take care of cherry-picking pull requests submitted here.

Trivia

The name dagger refers to two things:

  • a good mathematical framework for giving a semantics to probabilistic programming is a certain dagger category of Markov kernels, see eg this or that paper; Bayesian inversion corresponds to a particular symmetry of a mathematical structure and this symmetry is denoted using the † symbol.

  • the underlying representation of the probabilistic model when using the incrementalized backend is as a directed acyclic graph (ie a DAG, which sounds exactly like the French translation of dagger)
