Computationally-efficient initialisation of GPs: The generalised variogram method

1 code implementation11 Oct 2022 Felipe Tobar, Elsa Cazelles, Taco de Wolff

We present a computationally-efficient strategy to initialise the hyperparameters of a Gaussian process (GP) avoiding the computation of the likelihood function.

A novel notion of barycenter for probability distributions based on optimal weak mass transport

no code implementations NeurIPS 2021 Elsa Cazelles, Felipe Tobar, Joaquín Fontbona

We introduce weak barycenters of a family of probability distributions, based on the recently developed notion of optimal weak transport of mass by Gozlanet al. (2017) and Backhoff-Veraguas et al. (2020).

The Wasserstein-Fourier Distance for Stationary Time Series

1 code implementation11 Dec 2019 Elsa Cazelles, Arnaud Robert, Felipe Tobar

The WF distance operates by calculating the Wasserstein distance between the (normalised) power spectral densities (NPSD) of time series.
