3.4. Clustering and Density Estimation After training, data points can be clustered using the Gaussian Mixture Model. For each data point, the cluster with the highest posterior probability is assigned. Therefore, Gaussian Mixture Models for density estimation can be used to estimate the probability ...
Gaussian mixture models In Section 3.4 of this book, we discussed GMM as a fuzzy clustering tool. In the field of computer vision, GMM is widely applied as a means of soft classification, which is conceptually similar to fuzzy clustering. For example, when implementing the Bags of Visual Word...
1. The Dirichlet Multivariate Normal Mixture Model The first Dirichlet Process mixture model that we will examine is the Dirichlet Multivariate Normal Mixture Model which can be used to perform clustering on continuous datasets. The mixture model is defined as follows: Equation 1: Dirichlet Multivariat...

We propose a compressed 3D Gaussian splat representation that utilizes sensitivity-aware vector clustering with quantization-aware training to compress directional colors and Gaussian parameters. The learned codebooks have low bitrates and achieve a compression rate of up to 31× on real-world scenes ...
Dirichlet processes (DPs) have been successfully applied to the clustering of data into an unknown number of clusters because they allow for the creation and deletion of clusters, as necessary, while new data is obtained over time. Let (A,B) be a measurable space, where B is a σ-algebra...
