Fair Marriage Principle and Initialization Map for the EM Algorithmstat.ML

Paper refutes EM convergence theory and introduces a new EM algorithm.

problem The convergence theory of the EM algorithm is incorrect and affects its performance.

method Proposes a new EM algorithm called the Channel Matching (CM) EM algorithm and provides an initialization map.

result The locally maximal Q can affect the convergent speed but not the global convergence.
