[June 28, 2020] I am very pleased to announce that my paper with Michael Perlmutter, Feng Gao, and Guy Wolf entitled Geometric Scattering Networks on Compact Riemannian Manifolds has been accepted to the Mathematical and Scientific Machine Learning (MSML) conference. This is the first edition of the MSML conference, and we are very excited to be a part of it. In this paper we extend the wavelet scattering transform to compact Riemannian manifolds and use this extension as a model for deep networks on such manifolds. We prove that these networks are provably invariant to isometry group actions, and stable to diffeomorphism actions on input signals supported on the manifold. This paper is part of a series of works on geometric wavelet scattering networks on graphs and manifolds, but is our first comprehensive manifold-based paper (there was a preliminary version of this work in NeurIPS workshop in 2018).
[June 14, 2020] Guy Wolf and I are organizing an online SIAM MDS mini-symposium on “Deep thoughts on geometric learning & exploration of non-Euclidean data.” It will be held June 17 and June 24 and we have a great list of speakers. Anyone can join via Zoom – more information here. UPDATE [June 27, 2020]: The mini-symposium has concluded! Slides from the talks can be found on the mini-symposium page.
[April 27, 2020] There is an exciting online seminar series on the Mathematics of INformation, Data, and Signals (MINDS), with a really great list of speakers. Anyone can join virtually through Zoom, you just need to sign up through the Google form here.
