Introduction,t in order to make distinctions without having to employ very high-dimensional spaces, a curved Riemannian manifold may work well. It is then a basic task of geometric data analysis to construct or approximate such a Riemannian manifold from finitely many data points.

Metric Spaces and Manifolds,ric in detail, including the exponential map and normal coordinates, sectional and Ricci curvatures, Jacobi fields and the Laplace-Beltrami operator. We conclude the chapter by discussing other important geometries and introducing the concept of largitude in order to quantify how much a metric space spreads out in different directions.

Topological Foundations, Hypercomplexes and Homology,ures like (differentiable) manifolds, and from measure theory for quantifying sizes. Homology plays a fundamental role, as a scheme for assigning algebraic invariants to geometric objects by systematically using cancellations. This then also allows us to describe a powerful scheme of topological data analysis, persistent homology.

Averaging is the principle behind Laplace operators, and in this chapter, we both provide an abstract treatment and specific applications, for instance to image denoising.

Of course, to be successfully applied, the geometric tools usually need to be redefined, generalized, or extended appropriately..Pri
