上一次我们谈到了用 k-means 进行聚类的方法,这次我们来说一下另一个很流行的算法:Gaussian Mixture Model (GMM)。事实上,GMM 和 k-means 很像,不过 GMM 是学习出一些概率密度函数来(所以 GMM 除了用在 clustering 上之外,还经常被用于 density estimation ),简单地说,k-means 的结果是每个数据点被 assign ...
The Gauss- ian mixture reduction via clustering (GMRC) merging algorithm consists of a pre- processing, clustering, and an optional refinement step. In the preprocessing step, a preliminary solution to the reduced GM (38) is obtained using Runnalls' merging algorithm [47], where the resulting...

Sklearn.mixture.GMM(n_components=1, covariance_type=’diag’, random_state=None, thresh=None, tol=0.001,...) 高斯混合模型。 展示高斯混合模型概率分布,这可以轻松评估GMM分布的参数,从中采样,及对GMM分布的参数进行最大似然估计。 初始化参数,以使每个混合成分具有零均值和相同性协方差。
For cluster to provide meaningful results when clustering new data, X0 should come from the same population as X, the original data used to create the mixture distribution. In particular, when computing the posterior probabilities for X0, cluster and posterior use the estimated mixing probabilities...
Probabilistic clustering with Gaussian Mixture Models 用基于概率的高斯混合模型聚类 In KMeans, we assume that the variance of the clusters is equal. This leads to a subdivision of space that determines how the clusters are assigned; but, what about a situation where the variances are not equal ...
Demonstration of Gaussian mixture models for classification. See :ref:`gmm` for more information on the estimator. Plots predicted labels on both training and held out test data using a variety of GMM classifiers on the iris dataset. Compares GMMs with spherical, diagonal, full, and tied covaria...
