“…A main goal of topological data analysis (TDA) is to characterize the structure of an object-usually a point cloudthrough its topological features. In particular, persistent homology [2,21] is a family of techniques that detect and summarize multiscale topological features and has been applied to a wide variety of applications including timeseries data [10,24], image processing [31], machine learning [19], and artificial intelligence [3,17]. Complementing the study of point-cloud data, another line of research involves utilizing the TDA toolset to study complex systems, for which applications include the analysis of spreading processes over social networks [28], network neuroscience [5,25], mechanical-force networks [12], jamming in granular material [13], molecular structure [16], and DNA folding [7].…”
