Statistical Persistent Homology

Persistent homology is a method for probing topological properties of point clouds and functions. The method involves tracking the birth and death of topological features as one varies a tuning parameter. Features with short lifetimes are informally considered to be “topological noise.” In our work, we attempt bring some statistical ideas to persistent homology. In particular, we have derived confidence intervals that allow us to separate topological signal from topological noise.
