Goals

High dimensional geometric data are ubiquitous in science and engineering, and thus processing and analyzing them is a core task in these disciplines. Recently, a new geometric and topological approach to data analysis has emerged, extending the success story of geometric algorithms with guarantees to high-dimensions. This course is an introduction to the new field of Computational Geometry Learning providing mathematical and algorithmic foundations to geometric sampling and approximation.

This course is related to a new European project called CG-Learning (Computational Geometry Learning) and involving research groups at INRIA Saclay, INRIA Sophia Antipolis, ETH Zurich, and in the universities of Iena, Dortmund, Berlin, Gronningen, Athens and Tel Aviv.

Language

The course will be given in english, except if all participants speak french fluently.
Slides and course notes are in english.

Organisation

The course will include 10 sessions of 2h30 each.
Each lecture will include exercises.

Course planning

Part I. Geometric data structures

Part II. Sampling theory and shape reconstruction

Part III. Topological data analysis
