Abstract Model image segmentation problem by normalized cuts, then solve the relaxed normalized cuts problem using spectral clustering. NotationsGG: G=(V,E)G=(V,E) be an undirected graph with vertex

本文记录了EM算法求解混合伯努利分布的推导，并提供了matlab实验代码。

本文从高斯混合模型出发，引出EM算法，最后回归到利用EM算法求解高斯混合模型。理论部分力求详尽不留证明疑点，所以略显冗长。实验部分给出了生成高斯混合分布样本和利用EM算法求解高斯混合模型的matlab代码。
