In this chapter, bounded asymmetric Gaussian mixture model (BAGMM) is proposed. In the described model, parameter estimation is performed by maximization of log-likelihood via expectation–maximization (EM) and Newton–Raphson algorithm. This model is applied to several applications for data clustering...
二元/二维只是多元的一个特例,现在将问题延伸到多元/多维高斯/正态分布概率密度函数的推导上。多元高斯分布在很多场景下都有用,比如高斯混合模型(Gaussian Mixture Model)中,每个组件都是单个多元高斯分布,样本不仅是一维的,现实中大多是数据样本都是多维的。只有真正弄清楚公式的来龙去脉,来能更好的编写程序,进行实...

This contribution is devoted to the degeneracy problem occuring when considering the maximum likelihood estimator in the case of multivariate Gaussian mixture modeling. We show that the likeli-hood function is unbounded and we characterize the set of singularity points. We also show that the penalizat...

SampleQC is implemented as an R package based on a robust multivariate Gaussian mixture model (GMM). By fitting a mixture model in which each of the mixture components corresponds to one “QC cell type,” SampleQC identifies the QC distributions for multiple cell types simultaneously, removing ...
