Fast inference of latent space dynamics in huge relational event networks

no code implementations29 Mar 2023 Igor Artico, Ernst Wit

Bayesian and EM-type algorithms have been proposed for inferring the latent space, but both the sheer size many social network applications as well as the dynamic nature of the process, and therefore the latent space, make computations prohibitively expensive.

Reproducing kernel Hilbert space based estimation of systems of ordinary differential equations

no code implementations14 Nov 2013 Javier González, Ivan Vujačić, Ernst Wit

Non-linear systems of differential equations have attracted the interest in fields like system biology, ecology or biochemistry, due to their flexibility and their ability to describe dynamical systems.
