In this talk, we will focus on computational tools for the analysis of large size datasets equipped with multiple scalar values. We will consider multi-persistent homology, an extension of persistent homology motivated by the need to analyze properties of data characterized by several parameters. We will present a new approach to multi-persistent homology computation based on reducing the input complex through the definition of a discrete gradient field inspired by discrete Morse theory.
