EM演算法及其推廣-expectation maximization algorithm

WIKI

In statistics, an expectation–maximization (EM) algorithm is an iterative method to find maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables.

  • EM演算法是一種迭代演算法

  • 用於含有隱變數的概率模型引數的極大似然估計,或極大後驗概率估計
