Explore clustering with tangles in this 57-minute conference talk by Ulrike von Luxburg and Solveig Klepper. Delve into the formal framework, agreement parameters, and cost functions of this clustering approach. Examine simple examples, postprocessing techniques, and soft hierarchical dendrograms. Learn about interpretable cuts, stochastic block models, and Gaussian mixture models. Discover theoretical guarantees for Gaussian mixtures and potential applications. Recorded during the "Machine Learning and Signal Processing on Graphs" thematic meeting at the Centre International de Rencontres Mathématiques in Marseille, France.
