Figaro is a probabilistic programming language that supports development of very rich probabilistic models and provides reasoning algorithms that can be applied to models to draw useful conclusions from evidence. Both model representation and reasoning algorithm development can be challenging tasks.
Figaro makes it possible to express probabilistic models using the power of programming languages, giving the modeler the expressive tools to create a wide variety of models. Figaro comes with a number of built-in reasoning algorithms that can be applied automatically to new models. In addition, Figaro models are data structures in the Scala programming language, which is interoperable with Java, and can be constructed, manipulated, and used directly within any Scala or Java program.
Figaro is free and is released under an open-source license. The current, stable binary release of Figaro can be found here. For more information please see the Figaro Release Notes and Figaro Tutorial. Documentation of the Figaro library interface can be found here.
