Witryna3 lut 2024 · 1 Gaussian Mixture Models (GMM) Examples in which using the EM algorithm for GMM itself is insufficient but a visual modelling approach appropriate can be found in [Ultsch et al., 2015]. In general, a GMM is explainable if the overlapping of Gaussians remains small. An good example for modeling of such a GMM in the … Witryna5 kwi 2024 · Provides the following types of models: Models for contingency tables (i.e. log-linear models) Graphical Gaussian models for multivariate normal data (i.e. covariance selection models) Mixed interaction models. huge: High-dimensional Undirected Graph Estimation. lvnet: Latent Variable Network Modeling.
