This post is a bit of a misnomer, as we will not be defining or going into great detail about the actual persistent homology groups. Instead, we will focus more on Betti numbers , which are derived from the persistent homology groups, and are more useful to data scientists.
WebPersistent homology (PH) is one of the most popular methods in Topological Data Analysis. Even though PH has been used in many different types of applications, the reasons behind its success remain elusive; in particular, it is not known for which classes of problems it is most effective, or to what extent it can detect geometric or topological ... WebOne of the most popular TDA tools is persistent homology [71, 28]. This paper focuses on the application of an extension of this called multi-parameter persistent homology [17]. Speci cally, we make extensive use of a new software tool for working with 2-parameter persistent homology called RIVET (the Rank Invariant Visualization
