Optimal Quantisation of Probability Measures Using Maximum Mean Discrepancy

AISTATS 2021poster

Several researchers have proposed minimisation of maximum mean discrepancy (MMD) as a method to quantise probability measures, i.e., to approximate a distribution by a representative point set. We consider sequential algorithms that greedily minimise MMD over a discrete candidate set. We propose a n…

Approximate simulation of linear continuous time models driven by asymmetric stable Lévy processes

ICASSP 2017accepted

In this paper we extend to the multidimensional case the modified Poisson series representation of linear stochastic processes driven by α-stable innovations. The latter has been recently introduced in the literature and it involves a Gaussian approximation of the residuals of the series, via the ex…
