飞夺泸定桥

摘要： （1）以下matlab代码实现了高斯混合模型：function [Alpha, Mu, Sigma] = GMM_EM(Data, Alpha0, Mu0, Sigma0)%% EM 迭代停止条件loglik_threshold = 1e-10;%% 初始化参数[dim, N] = size(Data);M = size(Mu0,2);loglik_old = -realmax;nbStep = 0;Mu = Mu0;Sigma = Sigma0;Alpha = Alpha0;Epsilon = 0.0001; while (nbStep < 1200) nbStep = nbStep+ 阅读全文
