Probing omics data via harmonic persistent homology

1 code implementation10 Nov 2023 Davide Gurnari, Aldo Guzmán-Sáenz, Filippo Utro, Aritra Bose, Saugata Basu, Laxmi Parida

Identifying molecular signatures from complex disease patients with underlying symptomatic similarities is a significant challenge in the analysis of high dimensional multi-omics data.

Euler Characteristic Curves and Profiles: a stable shape invariant for big data problems

1 code implementation3 Dec 2022 Paweł Dłotko, Davide Gurnari

While being a weaker invariant in one dimension, we show that Euler Characteristic based approaches do not possess some handicaps of persistent homology; we show efficient algorithms to compute them in a distributed way, their generalization to multifiltrations and practical applicability for big data problems.
