Sierpiński--Knopp Wasserstein Distance for Persistence Diagrams and Applications to 2-Wasserstein Approximation

Sebastien Tchitchek, Julien Tierny

This paper introduces the Sierpiński-Knopp (SK) Wasserstein distance, a fast metric between persistence diagrams. The SK-Wasserstein distance, denoted dSK​, maps diagr…

Continuous Edit Distance, Geodesics and Barycenters of Time-varying Persistence Diagrams

Sebastien Tchitchek, Mohamed Kissi, Julien Tierny

We introduce the Continuous Edit Distance (CED), a geodesic and elastic distance for time-varying persistence diagrams (TVPDs). The CED extends edit-distance ideas to TVPDs by comb…
