Open source software for reactive, efficient and scalable Bayesian inference.

Welcome to the Reactive Bayes organization! We develop and maintain a suite of Julia packages for probabilistic programming and Bayesian inference with a focus on reactive and message-passing based inference algorithms.

• RxInfer The central high-level probabilistic programming framework that enables reactive Bayesian inference on factor graphs through reactive message passing. It integrates tools including probabilistic graphical model definition and reactive message-based Bayesian inference.
• ReactiveMP An efficient message passing-based Bayesian inference engine that implements the core algorithms and rules for performing high-performance, reactive message passing on factor graphs.
• GraphPPL A probabilistic programming language for specifying probabilistic graphical models as factor graphs. It provides a high-level domain-specific language for model creation and works seamlessly with RxInfer for inference.
• ExponentialFamily Extends Distributions.jl with comprehensive implementations of a collection of exponential family distributions.
• Rocket A reactive programming framework providing core primitives for event handling and streaming for Julia, inspired by RxJS. It forms the backbone for reactive computations in the ecosystem.

• ExponentialFamilyManifolds Provides manifold representations of exponential family distributions, enabling advanced optimization workflows with Manopt.jl. It facilitates efficient parameter tuning in natural parameter spaces.

• ExponentialFamilyProjection Enables projection of (un-normalized) log probability density functions onto exponential family distributions. It uses optimization techniques from Manopt.jl and leverages ExponentialFamilyManifolds.jl.

• BayesBase Defines and re-exports core methods and utilities for Bayesian computation. It provides a shared foundation for the Reactive Bayes ecosystem.

• RxInferExamples Contains example applications using RxInfer.
• RxEnvironments Provides reactive environments for agents.

Our packages are designed to work together seamlessly to provide:

• Reactive Inference: Real-time updates as new data arrives
• Message Passing: Efficient inference through local computations
• Scalability: Handle large models and datasets
• Flexibility: Mix and match components for your specific needs
