Kernel-based function learning in dynamic and non stationary environments

no code implementations4 Oct 2023 Alberto Giaretta, Mauro Bisiacco, Gianluigi Pillonetto

This includes the important exploration-exploitation problems where e. g. a set of agents/robots has to monitor an environment to reconstruct a sensorial field and their movements rules are continuously updated on the basis of the acquired knowledge on the field and/or the surrounding environment.

Absolute integrability of Mercer kernels is only sufficient for RKHS stability

no code implementations2 May 2023 Mauro Bisiacco, Gianluigi Pillonetto

Working in continuous-time, it is the purpose of this note to prove that the same result holds also for Mercer kernels.

On the stability test for reproducing kernel Hilbert spaces

no code implementations1 May 2023 Mauro Bisiacco, Gianluigi Pillonetto

Reproducing kernel Hilbert spaces (RKHSs) are special Hilbert spaces where all the evaluation functionals are linear and bounded.

Sliding-mode theory under feedback constraints and the problem of epidemic control

no code implementations12 Sep 2021 Mauro Bisiacco, Gianluigi Pillonetto

It is only apparently confined to the linear setting and allows also to study an important set of nonlinear models.

Epidemiology

COVID-19 epidemic control using short-term lockdowns for collective gain

no code implementations2 Sep 2021 Mauro Bisiacco, Gianluigi Pillonetto

In this paper we show that the Australian model can be generalized and given a rigorous mathematical analysis, casting strategies of the type short-term pain for collective gain in the context of sliding-mode control, an important branch of nonlinear control theory.

Mathematical foundations of stable RKHSs

no code implementations6 May 2020 Mauro Bisiacco, Gianluigi Pillonetto

Overall, our new results provide novel mathematical foundations of stable RKHSs with impact on stability tests, impulse responses modeling and computational efficiency of regularized schemes for linear system identification.

Computational Efficiency

Kernel absolute summability is only sufficient for RKHS stability

no code implementations5 Sep 2019 Mauro Bisiacco, Gianluigi Pillonetto

Many of them model unknown impulse responses exploiting the so called Reproducing Kernel Hilbert spaces (RKHSs) that enjoy the notable property of being in one-to-one correspondence with the class of positive semidefinite kernels.
