  • Radon–Wasserstein Gradient Flows for Interacting-Particle Sampling in High Dimensions

    Radon–Wasserstein Gradient Flows for Interacting-Particle Sampling in High Dimensions arXiv:2602.05227v1 Announce Type: new Abstract: Gradient flows of the Kullback–Leibler (KL) divergence, such as the Fokker–Planck equation and Stein Variational Gradient Descent, evolve a distribution toward a target density known only up to a normalizing constant. We introduce new gradient flows of the KL divergence with…

  • Conformalised Conditional Normalising Flows for Joint Prediction Regions in time series

    Conformalised Conditional Normalising Flows for Joint Prediction Regions in time series arXiv:2411.17042v1 Announce Type: new Abstract: Conformal Prediction offers a powerful framework for quantifying uncertainty in machine learning models, enabling the construction of prediction sets with finite-sample validity guarantees. While easily adaptable to non-probabilistic models, applying conformal prediction to probabilistic generative models, such as Normalising…
