Archetypal Analysis++: Rethinking the Initialization Strategy

no code implementations31 Jan 2023 Sebastian Mair, Jens Sjölund

Archetypal analysis is a matrix factorization method with convexity constraints.

Principled Interpolation in Normalizing Flows

no code implementations22 Oct 2020 Samuel G. Fadel, Sebastian Mair, Ricardo da S. Torres, Ulf Brefeld

In this paper, we solve this issue by enforcing a fixed norm and, hence, change the base distribution, to allow for a principled way of interpolation.

Coresets for Archetypal Analysis

1 code implementation NeurIPS 2019 Sebastian Mair, Ulf Brefeld

Archetypal analysis represents instances as linear mixtures of prototypes (the archetypes) that lie on the boundary of the convex hull of the data.
