Bala Krishnamoorthy (9/16/20): Steinhaus filtration and stable paths in the Mapper

Title: Steinhaus Filtration and Stable Paths in the Mapper Abstract: Two central concepts of topological data analysis are persistence and the Mapper construction. Persistence employs a sequence of objects built on data called a filtration. A Mapper produces insightful summaries of data,
