WebPersistent homology is a mathematical tool from topological data analysis. It performs multi-scale analysis on a set of points and identiﬁes clusters, holes, and voids therein. These latter topologi- cal structures complement standard feature repre- sentations, making persistent homology an attrac- tive feature extractor for artiﬁcial intelligence.
