Entropy Message Passing Algorithm
Message passing over factor graph can be considered as generalization of many well known algorithms for efficient marginalization of multivariate function. A specific instance of the algorithm is obtained by choosing an appropriate commutative semiring for the range of the function to be marginalized. Some examples are Viterbi algorithm, obtained on max-product semiring and forward-backward alg...
متن کاملEntropy Message Passing
The paper proposes a new message passing algorithm for cycle-free factor graphs. The proposed ”entropy message passing” (EMP) algorithm may be viewed as sumproduct message passing over the entropy semiring, which has previously appeared in automata theory. The primary use of EMP is to compute the entropy of a model. However, EMP can also be used to compute expressions that appear in expectation...

متن کاملApproximate Message Passing
In this note, I summarize Sections 5.1 and 5.2 of Arian Maleki’s PhD thesis. 1 Notation We denote scalars by small letters e.g. a, b, c, . . ., vectors by boldface small letters e.g. λ,α,x, . . ., matrices by boldface capital letter e.g. A,B,C, . . ., (subsets of) natural numbers by capital letters e.g. N,M, . . .. We denote i’th element of a vector a by ai and (i, j)’th entry of a matrix A by ...
متن کاملBiclustering Using Message Passing
Biclustering is the analog of clustering on a bipartite graph. Existent methods infer biclusters through local search strategies that find one cluster at a time; a common technique is to update the row memberships based on the current column memberships, and vice versa. We propose a biclustering algorithm that maximizes a global objective function using message passing. Our objective function c...
