Gaussian mixture models(GMMs) assign each observation to a cluster by maximizing the posterior probability that a data point belongs to its assigned cluster. Create a GMM objectgmdistributionby fitting a model to data (fitgmdist) or by specifying parameter values (gmdistribution). Then, use object...
从中心极限定理的角度上看,把混合模型假设为高斯的是比较合理的,当然也可以根据实际数据定义成任何分布的Mixture Model,不过定义为高斯的在计算上有一些方便之处,另外,理论上可以通过增加Model的个数,用GMM近似任何概率分布。 混合高斯模型的定义为: 其中K为模型的个数,πk为第k个高斯的权重,则为第k个高斯的概率...

20.2.2.2Gaussian mixture models Gaussianmixture models (GMMs) are another common approach for unsupervised clustering. The primary difference between these approaches and the k-means clustering approach discussed before is that GMMs assume that theprobability density function(PDF) of the entire dataset is...

高斯混合模型(Gaussian Mixture Models)是一种无监督聚类模型。GMM认为不同类别的特征密度函数是不一样的(实际上也不一样),GMM为每个类别下的特征分布都假设了一个服从高斯分布的概率密度函数: 而数据中又可能是由多个类混合而成,所以数据中特征的概率密度函数可以使用多个高斯分布的组合来表示: ...
