Geometry, Topology and Statistics in Data Sciences

10-14 October - IHP, Paris

On one hand, modern data science makes use of Topological Data Analysis in a preliminary step to obtain structural information before processing supervised or unsupervised methods. On the other hand, when a priori knowledge of a Riemannian manifold containing the data is available, shape analysis proposes to adapt mathematical statistics tools to infer geometric and statistical properties.

Lunches (Info handout)

  • Institut Henri Poincaré’s neighborhood has plenty of diverse food places.
    The two-hour lunch breaks give you enough time to eat in a restaurant, or to grab something to take away.
