Registration of algebraic varieties using Riemannian optimization

1 code implementation16 Jan 2024 Florentin Goyens, Coralia Cartis, Stéphane Chrétien

Our approach is particularly useful when the two point clouds describe different parts of an objects (which may not even be overlapping), on the condition that the surface of the object may be well approximated by a set of polynomial equations.

Nonlinear matrix recovery using optimization on the Grassmann manifold

1 code implementation13 Sep 2021 Florentin Goyens, Coralia Cartis, Armin Eftekhari

We investigate the problem of recovering a partially observed high-rank matrix whose columns obey a nonlinear structure such as a union of subspaces, an algebraic variety or grouped in clusters.
