A Representer Theorem for Hawkes Processes via Penalized Least Squares Minimization arXiv:2510.08916v1 Announce Type: new Abstract: The representer theorem is a cornerstone of kernel methods, which aim to estimate latent functions in reproducing kernel Hilbert spaces (RKHSs) in a nonparametric manner. Its significance lies in converting inherently infinite-dimensional optimization problems into finite-dimensional ones over dual…
