Researchers have introduced "Persistence Spheres," an enhanced method for representing measures, including persistence diagrams, within topological machine learning. This new approach offers a bi-continuous linear representation that is stable under 1-Wasserstein partial transport distance. The method is rooted in convex geometry and refines previous definitions to better align with partial transport mechanisms, encoding them via a signed diagonal augmentation. The updated persistence spheres have demonstrated competitive performance and improvements over existing methods in various machine learning tasks involving functional data, time series, and point clouds.
