Spring School on Geometric Methods in Data Science

13/02/23 - 17/02/23
Braude College of Engineering, Karmiel, Israel

The school will introduce participants to a wide range of geometric methods for analyzing data. Data points often come with some notion of distance between them, or can be arranged into a graph, a simplicial complex or a hypergraph, and that allows for the application of quantitative geometric methods. Topological data analysis looks at the dependence of the Betti numbers (certain topological invariants) on a metric scale parameter. Other methods consider the statistics of graph curvatures, concepts in discrete geometry formulated in analogy to Riemannian geometry, and these deliver local invariants that are easy to compute, but indirectly encode much global information. Such discrete curvatures will constitute a particular focus of the school, but we shall also cover a range of other methods, and in particular, applications in many diverse fields, from neuroscience to image analysis or robotics
