New cover!

AURORA is one of my fav artist, the river is the absolute banger that opens the album A Different Kind of Human. Here is a chill piano cover. Hope you enjoy!

Colon, question mark, ticking all the boxes

Also note that we limit ourselves to vanilla GNNs: no skip connections, normalization, etc classical anti-oversmoothing strategies. That's for the future!

7/7

Note that, while many optimization results are adapted from MLP to GNNs, here this is *specific* to GNNs: we show that this does not happen for MLPs.

6/7

...and that's bad! As soon as the last layer is trained (that happens immediately!), this average vanishes. The entire GNN is quickly stuck in a terrible near-critical point!
(*at every layers*, due to further mechanisms).

That's the main result of this paper.

5/7

...the "oversmoothing" of the backward signal is very particular: *when the forward is oversmoothed*, the updates to the backward are almost "linear-GNN" with no non-linearity.

So we *can* compute its oversmoothed limit! It is the **average** of the prediction error...

4/7

... but at the *middle* layers! Due to the non-linearity, it oversmoothes *when the forward is also oversmoothed* 😲

Why is it bad for training? Well...

3/7

The gradients are formed of two parts: the forward signal, and the backward "signal", initialized at the prediction error at the output then backpropagated.

Like the forward, the backward is multiplied by the graph matrix, so it will oversmooth...

2/7

New preprint! 🤓

"Backward Oversmoothing: why is it hard to train deep Graph Neural Networks?"

GNNs could learn to anti-oversmooth. But they generally don't. Why is that? We uncover many interesting stuff 🤔 1/7

Je sais pas si ça servira à quelque chose, mais je partage ici la réponse de John Tolan, l'un des pilotes du projet ERC sur le Coran européen, à propos de la polémique et des réactions sur le projet de recherche en question.

New cover! Like everyone I'm a bit obsessed with Expedition 33 right now, here is my version of the main track of the incredible OST :)

Cheers!

Hello! A small excerpt from our last rehearsal. Too Fast is a fantastic song by Camélia Jordana with a minimalist instrumentation. Hope you enjoy! :)

YouTube video by NK piano BLUE IN GREEN (Bill Evans) - Jazz Standards 003 (with MIDI)

Blue in Green has got to be one of the greatest jazz standard of all time, by the greatest jazz pianist, on the greatest jazz album. Definitely a fav of mine. Here is my humble, chillest version.

NeurIPS participation in Europe We seek to understand if there is interest in being able to attend NeurIPS in Europe, i.e. without travelling to San Diego, US. In the following, assume that it is possible to present accepted papers ...

Would you present your next NeurIPS paper in Europe instead of traveling to San Diego (US) if this was an option? Søren Hauberg (DTU) and I would love to hear the answer through this poll: (1/6)

"generative AI knows no bounds, it will unleash creativity on a scale never seen before 🤩"

*copies over and over whatever trend the CEO of a multibillion dollar company say is cool*

Know that if you work or interact with OpenAI in any way, shape or form, I have nothing but utter contempt for you right now. Utter contempt.
