Archetypal Analysis++: Rethinking the Initialization Strategy
Archetypal analysis is a matrix factorization method with convexity constraints.
Principled Interpolation in Normalizing Flows
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
Archetypal analysis represents instances as linear mixtures of prototypes (the archetypes) that lie on the boundary of the convex hull of the data.
Frame-based Data Factorizations
Archetypal Analysis is the method of choice to compute interpretable matrix factorizations.
