Study of the properties of convergence of the EM-algorithm in a probabilistic latent semantic analysis (English)
0 references
This paper introduces the basic concepts of probabilistic latent semantic analysis, presents deduction of expectation-maximization (EM) algorithm formulas and the pseudocodes. A theorem on the convergence rate of the EM algorithm is proved and superlinear convergence is formulated.
