## SumProductLab for Factor Graphs (Scripts) Publisher's description

### The SumProductLab provides a set of basic factor nodes for building up a factor graph

The SumProductLab provides a set of basic factor nodes for building up a factor graph. One can try out ideas by instantiating the necessary constraint nodes, connecting them up, and giving some evidence. The sum-product (or belief propagation) algorithm will compute the message to each node in the entire network. Finally, marginal probability of any variable in the graph can then be calculated.

Factor graphs can be used to model a wide range of systems. That means the same algorithm can be used to solve problems of different natures.

Examples are provided to demonstrate the usages of the pre-defined factor nodes. More information can be found in the included SumProductLab Reference. For startup and installation, please read the SumProductLab Quick Startup.
