A lesser-known fact about ML open source contributors: About 50% of code contributors to ML paper implementations are practitioners collaborating with researchers. Here are the topk researchers & practitioners contributing to open source and open to sponsorship.…

Layer-wise equivariance symmetries (e.g. conv layers) allow neural nets to generalise effectively. But can we learn them automatically using gradients? We show we can! Excited to share that our method ELLA has been accepted as a spotlight paper at . A thread.👇1/11🧵

Had an incredible time hosting the inaugural Paris Learning-on-Graphs Meetup! 🎉 Thank you to everyone who attended and made it such a fantastic hybrid event! Special thanks to our inspiring speakers for their outstanding talks and to the poster presenters for sharing their work.

The perpetually undervalued least-squares:

minₓ‖y−Ax‖²

can teach a lot about some complex ideas in modern machine learning including overfitting & double-descent.

Let's assume A is n-by-p. So we have n data points and p parameters

The supremacy of search as a paradigm—and the associated attention-selling business—is coming to an end.

Virtual assistants will disrupt search like search disrupted web portals.

Note, a similar observation was made by Michaël Defferrard on spherical data, showing that with isotropic filters (only way to get equivariance without g-convs! cf. Lecture 1.7 uvagedl.github.io) one can beat specialized equiv layers like group convs

For those (virtually) at SIAM Imaging Science '22 : There's this amazing session on 'Learning from Vision'. I'll be speaking at 18.10 CET (times below in UTC-4) about equivariant graph NNs using sub-Riemannian geometry😎(cf arxiv.org/abs/2111.12139 w Michaël Defferrard & Aguettaz)

The essential nature of convolutions to space is the backbone of the thesis I'll defend today.

My contribution: generalized convolutions. They enable parameter sharing for non-transitive and unknown symmetry groups to efficiently learn on arbitrary domains.

Looking forward!

To make the implicit explicit:

I strongly believe we should ask students (and all researchers) to optimize quality over quantity.

But we can't honestly do that at the same time our orgs tweet 'we have 1000 NeurIPS papers.'

Let's normalize not caring about counts *EVERYWHERE*.

A classic! I love sub-Riemannian geometry and've been trying to get it back in my research. Inspired by the math, Aguettaz+Michaël Defferrard+I just put
“ChebLieNet: Invariant Spectral Graph NNs Turned Equivariant by Riemannian Geometry on Lie Groups” on arXiv: arxiv.org/abs/2111.12139 [1/4]
