First we introduce the abstract form of the EM algorithm. Then we develop the EM parameter estimation procedure for one application: finding the parameters of a mixture of Gaussian densities.

首先给出em算法的抽象形式，然后研究EM参数估计方法的一个应用：求高斯混合密度的参数。

The ORB would then intercept the message and be responsible for finding an object that could implement the request, pass it the parameters, invoke its method, and return the results.

ORB 截获这条消息，并负责搜索一个能执行该请求的对象，将参数传递给它，调用它的方法，然后返回结果。
