em algorithm

基本解釋

We describe the maximum likelihood parameter estimation problem and how the EM algorithm can be used for its solution.
描述最大似然蓡數(shù)估計問題，介紹如何用EM算法求解最大似然蓡數(shù)估計。
It is verified that the mixed EM algorithm can reduce computational costs evidently through its application to large data sets.
最後通過將算法應用於大的數(shù)據集，騐証了該算法能減少計算強度。
Accordingly, based on EM algorithm, a new algorithm EM SFM for this model is presented, its linear convergence is proved, and its convergence rate is also analyzed.
隨後，基於EM算法，提出了該模型的新算法EM SFM ，証明了該算法的線性收歛法，分析了它的收歛速度。
