Deep Learning and Geometric Deep Learning: an introduction for mathematicians and physicists

no code implementations9 May 2023 R. Fioresi, F. Zanchetta

In this expository paper we want to give a brief introduction, with few key references for further reading, to the inner functioning of the new and successfull algorithms of Deep Learning and Geometric Deep Learning with a focus on Graph Neural Networks.

A precortical module for robust CNNs to light variations

no code implementations15 Feb 2022 R. Fioresi, J. Petkovic

We present a simple mathematical model for the mammalian low visual pathway, taking into account its key elements: retina, lateral geniculate nucleus (LGN), primary visual cortex (V1).
