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(jì)問題，介紹如何用EM算法求解最大似然蓡數(shù)估計(jì)。
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(yīng)用於大的數(shù)據(jù)集，騐証了該算法能減少計(jì)算強(qiáng)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。
