使用python语言，加以清楚注释，借用经典的三硬币模型实现了EM算法的简单应用，并附生成数据的简单代码(The python language is used to make clear annotations and to use the classic three coin model to implement the simple application of the EM algorithm and to attach the simple code to generate the d

EM算法是人工智能十大算法之一。三硬币模型算例出自李航的《统计学习方法》，书中给出了计算结果和简单解说，对于不是学数学的看这种复杂的公式看不懂，我也看了很久才看懂。我用matlab编写的代码，并作了详细的注释。(EM algorithm is one of the ten major algorithms of artificial intelligence. The three coin model is derived from Li Hang's statistical learning
