X-means的假设:identical spherical assumption 数据由X个高斯函数残生,每个高斯函数有一样的方差σσ(每个维度上的变量不相关,协方差矩阵为diag(σ)diag(σ))、不同的μiμi; 数据生成时,根据概率pipi选择一个高斯函数gigi,然后生成一个点 所以似然函数为: ...
1、X-means:一种针对聚类个数的K-means算法改进摘要尽管 K-means 很受欢迎,但是他有不可避免的三个缺点:1、它的计算规模是受限的。2、它的聚类个数 K 必须是由用户手动指定的。3、它的搜索是基于局部极小值的。在本文中,我们引入了前两种问题的解决办法,而针对最后一个问题,我们提出了一种局部补救的措施...

机器学习三-xmeans 查看原文 Python实现基于BIC的语音对话分割(二) 1. 语音多分割点检测 在上一篇博客<Python实现基于BIC的语音对话分割(一)>中,我们介绍了基于BIC(贝叶斯信息准则)的语音分割问题,有一个假设是这段语音中只有一个分割点,即...直到wEnd超过整个语音的结束点,停止检测过程。 可以参看下面这个形象...
Despite its popularity for general clustering, K-means suffers three major shortcomings; it scales poorly computationally, the number of clusters K has to be supplied by the user, and the search is prone to local minima. We propose solutions for the first two problems, and a partial remedy fo...
Well, it means a kiss.The more kisses, the more affection you are showing. 好吧,它指的是亲吻。亲吻越多,你表现出的感情越多。 Where does this concept of putting an X to mean a kiss come from?Dr LauraWright is from the Faculty of English ...
