Dimple is a software tool that performs inference and learning on probabilistic graphical models.  The inference can be performed with belief propagation algorithms or sampling based algorithms.  Dimple is open source and is maintained as a Github project.

Features include
  • MATLAB and Java APIs.
  • Inference techniques include the sum-product, min-sum, particle BP, and Gibbs algorithms.
  • Supports arbitrary discrete variables.
  • Some solvers support continuous variables (namely Particle BP, Gibbs, and Gaussian)
  • Allows rapid prototyping of complicated graphical models by describing connectivity with simple associations of factors with variables.
  • Supports nested graphs.
  • Rolled up graphs.
  • Implements some parameter learning.
