We propose a model-based approach to clustering the edges of a network using a latent space model describing the features of both actors and latent environments. We derive a generalized EM algorithm for estimation and gradient-based Monte Carlo algorithms, and we demonstrate that the computational ...

That is, the performance of four different categories of clustering algorithms (partition-based K-Means, model-based SOM, distribution-based GMM and hierarchy-based) known to consistently produce high-quality clusters and widely used for fault classification are compared. 3.2.1 Partition-based K-...
摘要: Agglomerative hierarchical clustering methods based on Gaussian probability models have recently shown promise in a variety of applications. In this approach, a maximum-likelihood pair of clusters ...关键词: hierarchical agglomeration mixture models model-based cluster analysis ...
Another study explored effective prediction models for discharge planning based on a machine learning algorithm derived from data gathered during hospitalization in the acute phase of ischemic stroke. That study found that the use of clustering learning algorithms permits the unsupervised identification of ...
we also compared the proposed scDCC model with traditional constrained clustering algorithms (COP K-means35and MPC K-means40). Since some competing methods could not handle large-scale datasets, we randomly sampled 2100 cells from each dataset to form the final experimental datasets. The down-sampl...
