Belief propagation code download

This is pretty fragile and not user-friendly. As is common in graph algorithms, these are defined recursively. Example 5. I can make sure I get the same values [0. Post History. In code, There are two classes in the graph: Variable and Factor. Both classes have a string representing the name and a list of neighbors. A Variable can only have Factors in its list of neighbors. A Factor can only have Variables. To represent the probability distribution, Factors also have a field for data.

These each will be a new Variable that are referenced from Factors below. Each term e. Then find all variables in this term "v1", "h1" and add the corresponding Variables as neighbors to the new Factor, and this Factor to the Variables' neighbors.

Now we can implement sum-product message passing. This is a preview of subscription content, access via your institution. Rent this article via DeepDyve. Arikan E. Channel polarization: a method for constructing capacity-achieving codes for symmetric binary-input memoryless channels.
