Topological Data Analysis Enhances Prototype Selection Methods

Researchers have introduced two novel prototype selection methods, Topological Prototype Selector (TPS) and Boundary-Conscious Topological Prototype Selector (BoundaryTPS), which leverage topological data analysis. These methods operate on the multi-scale topological structure of data, unlike traditional approaches. Evaluations on fifteen real datasets showed that these topological methods offer a different operating point in prototype selection, with BoundaryTPS outperforming several classical baselines in preserving H1 persistence diagrams and demonstrating greater stability under perturbation.
