Seriation of Toeplitz and latent position matrices: optimal rates and computational trade-offs
Clément Berenfeld, Alexandra Carpentier, Nicolas Verzelen
In this paper, we consider the problem of seriation of a permuted structured matrix based on noisy observations. The entries of the matrix relate to an expected quantification of i…

Estimating the reach of a manifold via its convexity defect function
Clément Berenfeld, John Harvey, Marc Hoffmann +1
The reach of a submanifold is a crucial regularity parameter for manifold learning and geometric inference from point clouds. This paper relates the reach of a submanifold to its c…

Density estimation on an unknown submanifold
Clément Berenfeld, Marc Hoffmann
We investigate density estimation from a -sample in the Euclidean space , when the data is supported by an unknown submanifold of possibly unknown dimension $d…
