Detailed explanation-1: -In contrast, Gaussian mixture models can handle even very oblong clusters. The second difference between k-means and Gaussian mixture models is that the former performs hard classification whereas the latter performs soft classification.
Detailed explanation-2: -Gaussian mixture models (GMMs) are often used for data clustering. You can use GMMs to perform either hard clustering or soft clustering on query data. To perform hard clustering, the GMM assigns query data points to the multivariate normal components that maximize the component posterior probability, given the data.
Detailed explanation-3: -The GaussianMixture object implements the expectation-maximization (EM) algorithm for fitting mixture-of-Gaussian models.
Detailed explanation-4: -K-Means is a simple and fast clustering method, but it may not truly capture heterogeneity inherent in Cloud workloads. Gaussian Mixture Models can discover complex patterns and group them into cohesive, homogeneous components that are close representatives of real patterns within the data set.
Detailed explanation-5: -Abstract. The traditional Gaussian Mixture Model (GMM) for pattern recognition is an unsupervised learning method.
