A class of kernel-based scalable algorithms for data science

Philippe G. LeFloch, Jean-Marc Mercier, Shohruh Miryusupov

We present several generative and predictive algorithms based on the RKHS (reproducing kernel Hilbert spaces) methodology, which, most importantly, are scale up efficiently with la…

The velocity jump Langevin process and its splitting scheme: long time convergence and numerical accuracy

Nicolaï Gouraud, Lucas Journel, Pierre Monmarché

The Langevin dynamics is a diffusion process extensively used, in particular in molecular dynamics simulations, to sample Gibbs measures. Some alternatives based on (piecewise dete…

On the quadratic stability of asymmetric Hermite basis with application to plasma physics with oscillating electric field

Ruiyang Dai, Bruno Després

We analyze why the discretization of linear transport with asymmetric Hermite basis functions can be instable in quadratic norm. The main reason is that the finite truncation of th…
