Gen Ecosystem

Gen is a platform for probabilistic modeling and inference. Gen includes a set of built-in languages for defining probabilistic models and a standard library for defining probabilistic inference algorithms, but is designed to be extended with an open-ended set of more specialized modeling languages and inference libraries.

Core packages

Gen

The main Gen package. Contains the core abstract data types for models and traces. Also includes general-purpose modeling languages and a standard inference library.

GenPyTorch

Gen modeling language that wraps PyTorch computation graphs.

GenTF

Gen modeling language that wraps TensorFlow computation graphs.

GenFluxOptimizers

Enables the use of any of Flux’s optimizers for parameter learning in generative functions from Gen’s static or dynamic modeling languages.

GenParticleFilters

Building blocks for basic and advanced particle filtering.

Contributed packages

GenPseudoMarginal

Building blocks for modular probabilistic inference using pseudo-marginal Monte Carlo algorithms.

GenVariableElimination

Compile portions of traces into factor graphs and use variable elimination on them.

Gen2DAgentMotion

Components for building generative models of the motion of an agent moving around a 2D environment.

GenDirectionalStats

Probability distributions and involutive MCMC kernels on orientations and rotations.

GenRedner

Wrapper for employing the Redner differentiable renderer in Gen generative models.

GenTraceKernelDSL

An alternative interface to defining trace translators.
