Fisher clustering
http://proceedings.mlr.press/v32/gopal14.html WebFeb 4, 2024 · Unsupervised learning of time series data, also known as temporal clustering, is a challenging problem in machine learning. Here we propose a novel algorithm, Deep Temporal Clustering (DTC), to naturally integrate dimensionality reduction and temporal clustering into a single end-to-end learning framework, fully unsupervised. …

Websphere. As an alternative to spherical k-means [2], mixtures of von Mises-Fisher (vMF) on this sphere have been shown to provided good clustering results, cf [3, 4, 5]. In this article, following [6], we propose a l 1 penalty for a mixture of von Mises-Fisher to induce sparsity of directional means and thus improve the understanding WebAbstract. This paper proposes three clustering-based discriminant analysis (CDA) models to address the problem that the Fisher linear discriminant may not be able to extract adequate features for satisfactory performance, especially for two class problems. The first CDA model, CDA-1, divides each class into a number of clusters by means of the ...
