Statistical learning on measures: an application to persistence diagrams

1 code implementation15 Mar 2023 Olympio Hacquard, Gilles Blanchard, Clément Levrard

We consider a binary supervised learning classification problem where instead of having data in a finite-dimensional Euclidean space, we observe measures on a compact space $\mathcal{X}$.

Topologically penalized regression on manifolds

no code implementations26 Oct 2021 Olympio Hacquard, Krishnakumar Balasubramanian, Gilles Blanchard, Clément Levrard, Wolfgang Polonik

We study a regression problem on a compact manifold M. In order to take advantage of the underlying geometry and topology of the data, the regression task is performed on the basis of the first several eigenfunctions of the Laplace-Beltrami operator of the manifold, that are regularized with topological penalties.
