Winter School 2017

Computational Geometry and Topology for Data Analysis

Jean-Daniel Boissonnat, Frédéric Cazals, Frédéric Chazal, Julien Tierny

January 23-27, 2017 – Inria Sophia Antipolis


This course is an introduction to Computational Geometry and Topology. It will introduce fundamental concepts, data structures and algorithms in this context. It can serve also as an introduction to the emerging field of Topological Data Analysis. Fundamental questions to be addressed are :

  • How can we represent complex shapes in high-dimensional spaces?
  • How can we infer properties of shapes from samples?
  • How can we handle noisy data?
  • How can we walk around the curse of dimensionality?
