Abstract

In order to provide theoretical explanations for the belief propagation(BP) algorithm often appear as non-convergence in the propositional formulas with more complex structure, this paper proposed the community discovery algorithm(WPLPA) based on warning propagation. It used the WPLPA algorithm to divide the community structure of the factor graph corresponding to the proposition formula by the message iteration strategy on the graph in BP algorithm, and established twodimensional structure entropy measurement model of the proposition formula with the help of the related theory and technology of two-dimensional structure entropy. It analyzed the relationship between the convergence of the BP algorithm and the twodimensional structure entropy through this model, and gave the convergence judgment of the BP algorithm. It systematically analyzed the convergence of BP algorithm. Experimental analysis proves that the method is effective and feasible, and it can provide theoretical support for the follow-up research of information dissemination algorithm.
