Charles River Analytics, developer of intelligent system solutions, announces
the release of Figaro 4.0, a probabilistic programming language that helps
people effectively reason, learn, and make decisions in the face of
uncertainty. Figaro 4.0 includes many new features, including a new technique
called Structured Factored
Inference<https://avipfeffer.wordpress.com/2016/03/16/celebrating-figaro-4-0-what-is-structured-factored-inference/>
(SFI), an alternative means of reasoning on a model. SFI decomposes a model
into smaller parts, which can then be solved by independently and combined
together to produce an answer. SFI can significantly improve inference time
since each portion of the model can be solved by the inference algorithm that
is most efficient on that specific part of the model.
Other new features in Figaro 4.0 include:
* New algorithms, including:
* Gibbs sampling on factor graphs
* Parallel Importance sampling and particle filtering
* Improvements to existing algorithms
* New tools for non-deterministic testing
* Added examples from the book, Practical Probabilistic
Programming<https://www.cra.com/company/news/charles-river-analytics-principal-scientist-releases-book-practical-probabilistic>
Figaro supports the development of rich probabilistic models and provides
reasoning algorithms to draw useful conclusions from the available "noisy"
evidence.
"Reasoning under uncertainty requires taking what you know and inferring what
you don't know," explained Dr. Avi Pfeffer, Principal Scientist at Charles
River. "Probabilistic reasoning is a well-established approach for reasoning
under uncertainty. Typically, we create a probabilistic model over all the
variables we're interested in, observe the values of some of these variables,
and query the model for values of other variables of interest. A number and
variety of approaches exist to handle this, and new approaches are being
developed. Figaro is designed help build and reason with this wide range of
probabilistic models."
Figaro is free and is released under an open-source license. For more
