Neural Approximation of Extended Persistent Homology on Graphs

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. WebThis work considers three fundamental shape analysis tasks: the detection of the number of holes, curvature and convexity from 2D and 3D point clouds sampled from … react os 64 bitWebOne of the most popular TDA tools is persistent homology [71, 28].
