On the effectiveness of persistent homology

Web8 de mar. de 2024 · This article aims to study the topological invariant properties encoded in node graph representational embeddings by utilizing tools available in persistent homology. Specifically, given a node embedding representation algorithm, we consider the case when these embeddings are real-valued. By viewing these embeddings as scalar … Web1 de fev. de 2024 · Abstract. In recent years, topological data analysis (TDA) has become a popular tool for studying 3D point clouds. Persistent homology is one of the most important tools of TDA, as it can extract the topological features hidden in a point cloud. However, the time-consuming computation of persistence diagrams severely limits the application of TDA.

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.
