Omega.jl

Omega.jl is a programming language for causal and probabilistic reasoning. It was developed by Zenna Tavares with help from Javier Burroni, Edgar Minasyan, Xin Zhang, Rajesh Ranganath and Armando Solar Lezama.

Quick Start

Omega is built in Julia. You can easily install it from a Julia repl with:

] add Omega

To use Omega, start with:

julia> using Omega

With that, see the Tutorial for a run through of the main features of Omega.

Contribute

We want your contributions!

  • Probabilistic models

Please add probabilistic models and model families to https://github.com/zenna/OmegaModels.jl

  • Inference procedures
