https://arxiv.org/abs/2409.17858 uses a reproducing kernel Hilbert space! everything old is new again. (haven’t read all of it)
https://journals.aps.org/prx/abstract/10.1103/PhysRevX.14.031001 How Deep Neural Networks Learn Compositional Data: The Random Hierarchy Problem. in the genre of paper “why do these things start working so well when they get big”
