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.
描述最大似然參數(shù)估計(jì)問題，介紹如何用EM算法求解最大似然參數(shù)估計(jì)。
It is verified that the mixed EM algorithm can reduce computational costs evidently through its application to large data sets.
最后通過將算法應(yīng)用于大的數(shù)據(jù)集，驗(yàn)證了該算法能減少計(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.
隨后，基于EM算法，提出了該模型的新算法EM SFM ，證明了該算法的線性收斂法，分析了它的收斂速度。
