Greedy algorithms for learning via exponential-polynomial splines

Rosanna Campagna, Stefano De Marchi, Emma Perracchione +1

Kernel-based schemes are state-of-the-art techniques for learning by data. In this work we extend some ideas about kernel-based greedy algorithms to exponential-polynomial splines,…

HJB-RBF based approach for the control of PDEs

Alessandro Alla, Hugo Oliveira, Gabriele Santin

Semi-lagrangian schemes for discretization of the dynamic programming principle are based on a time discretization projected on a state-space grid. The use of a structured grid mak…

Analysis of target data-dependent greedy kernel algorithms: Convergence rates for -, - and -greedy

Tizian Wenzel, Gabriele Santin, Bernard Haasdonk

Data-dependent greedy algorithms in kernel spaces are known to provide fast converging interpolants, while being extremely easy to implement and efficient to run. Despite this expe…

Analysis of Structured Deep Kernel Networks

Tizian Wenzel, Gabriele Santin, Bernard Haasdonk

In this paper, we leverage a recent deep kernel representer theorem to connect kernel based learning and (deep) neural networks in order to understand their interplay. In particula…
