New Persistence Spheres Method Enhances Topological Machine Learning

By PulseAugur Editorial · [1 sources] ·

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.

    Persistence Spheres: a Bi-continuous Linear Representation of Measures for Partial Optimal Transport

    arXiv:2603.15384v2 Announce Type: replace Abstract: We improve and extend persistence spheres, introduced in~\cite{pegoraro2025persistence}. Persistence spheres map an integrable measure $\mu$ on the upper half-plane, including persistence diagrams (PDs) as counting measures, to …
