An operator splitting analysis of Wasserstein--Fisher--Rao gradient flows
Francesca Romana Crucinio, Sahani Pathiraja
Wasserstein-Fisher-Rao (WFR) gradient flows have been recently proposed as a powerful sampling tool that combines the advantages of pure Wasserstein (W) and pure Fisher-Rao (FR) gr…
