Differential Equations and Nonlinear Analysis Seminar: Braxton Osting, University of Utah, Consistency of archetypal analysis
ZoomArchetypal analysis is an unsupervised learning method that uses a convex polytope to summarize multivariate data. For fixed k, the method finds a convex polytope with k vertices, called archetype points, such that the polytope is contained in the convex hull of the data and the mean squared distance between the data and the polytope…
