Webcussed on expressing hierarchical clustering in terms of probabilistic models. For example Ambros-Ingerson et at [2] and Mozer [10] developed models where the idea is to cluster data at a coarse level, subtract out mean and cluster the residuals (recursively). This paper can be seen as a probabilistic interpretation of this idea.

Web10 de abr. de 2024 · Gaussian Mixture Model ( GMM) is a probabilistic model used for clustering, density estimation, and dimensionality reduction. It is a powerful algorithm for discovering underlying patterns in a dataset. In this tutorial, we will learn how to implement GMM clustering in Python using the scikit-learn library. Webachieved naturally via hierarchical modeling; parameters are shared among groups, and the random-ness of the parameters induces dependencies among the groups. Estimates based on the posterior distribution exhibit “shrinkage.” In the current paper we explore a hierarchical approach to the problem of model-based clustering of grouped data.
