Preservation of Log-Concavity and Convergence of Wasserstein-Fisher-Rao Gradient Flows
Francesca Romana Crucinio, Sahani Pathiraja
We study the convergence of Wasserstein-Fisher-Rao (WFR) gradient flows for sampling from probability distributions known up to a normalisation constant. By combining Wasserstein t…
Properties and limitations of geometric tempering for gradient flow dynamics
Francesca Romana Crucinio, Sahani Pathiraja
We consider the problem of sampling from a probability distribution . It is well known that this can be written as an optimisation problem over the space of probability distribu…
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…
