Friends in Brittany! Next gig on nov. 8 😊 tell your friends and family 😎
Cheers!
I'm BEYOND THRILLED to tell you that our first original song is now available on all platforms!
Plz share if you like it 🙏🏼🙏🏼😊
Cheers
New cover! We continue the third album, with a bit of stompbox on the chorus. Cheers!

New cover with Blue Curl! Take it with me is an astoundingly beautiful love song by legendary songwriter Tow Waits. We've been playing this one since the very first gig!

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!

Let's start the third album !

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! :)

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.

Si vous passez en Bretagne, prochain concert avec Blue Curl le 24 mai !
En extérieur (abrité, c'est la Bretagne) avec buvette et food truck, viendez ça va être chouette !
Le directeur de la plateforme nous annonce une forte augmentation des chansons générées par l’IA. « Ces contenus sont désormais clairement signalés aux utilisateurs et sortent de l’algorithme », complète-t-il, se réjouissant que les auditeurs préfèrent les « vrais » artistes.
Playlist for my covers for the full second album of Coldplay!
Remember, we aim to cover *everything*

Aaand that's it for the second #coldplay album! Next up, we start X&Y...
