@KirkMSoodhalter Just making sure, you know who actually Krylov was? A tough man indeed.

The results of sanctions are absolutely the opposite. Now we have 90% of Putin support instead of 60% before, and they will blame not the Russian government. And this is a pure nationalism (to reject people based on their nationality or citizenship).

Here are three ingredients for metric learning SOTA: hyperbolic embeddings, vision transformer & contrastive loss. Pretraining is also important, this is a moment to shine for self-supervision. #CVPR2022 paper w/ Leyla, @vforvalya1, Nicu and @oseledetsivan https://t.co/0ReOiJyquR

@eeevgen @wellingmax I will! Very difficult to find the right words.

[Ivan Oseledets @oseledetsivan]

Some time ago @wellingmax posted about the Russia attacking Ukraine. For me, it was absolutely unimaginable. I was horribly wrong, and this whole situation is completely heartbreaking. It will have consequences inside Russia, I am pretty sure.

[Ivan Oseledets @oseledetsivan]

Yes, it was me, and it is exactly about what I wrote in this twitter post. Thanks for copying.

@oseledetsivan @wellingmax @oseledetsivan wasn’t it you who wrote that you were “sympathetic with the Russian leadership” “understanding the arguments of Putin” in the recognition of DNR/LNR?

[Ivan Oseledets @oseledetsivan]

@s_scardapane @atilimgunes @BAPearlmutter In fact, the parameters are updated as p_{k+1} = p_k - c_k v, where v is random, and c_k is directional derivative (can be approx. as f(p + eps*v) - f(p)). Thus, it is more or less a random search method (move in a random direction).

Check our latest ICLR'22 paper "When, Why, and Which Pretrained GANs Are Useful?" by Timofey Grigoryev, Artem Babenko, and myself. TL;DR: GAN initialisation is all about recall and Imagenet pretraining rocks.

@tomgoldsteincs Strictly speaking, there are two citations in the paper.

[Ivan Oseledets @oseledetsivan]

@arankomatsuzaki @CSProfKGD Well, this is exactly a random search method - you move in a random direction with a step size (and sign) determined by direction gradient. Surprising that it is competitive with stochastic gradient descent.

https://t.co/Xdrz5wQgLb - joint work with @vforvalya1 We formulate a surprising hypothesis about connection between optimal transport and DDPM models!

We present the new approximate backward functions which reduce the memory for activations. Interesting math behind!

@alidabouei If you write to me, I will surely answer :)

The world is perched on the edge of an abyss.

We may soon see the worst combat in Europe since WW2 – killing thousands of people, and raising the likelihood of nuclear war.

It didn't have to be this way. A thread. 1/N

[Ivan Oseledets @oseledetsivan]

@RWerpachowski @jatentaki @wellingmax Very democratic - if the opinion is different, call them trolls. In the same thread there is Victor Lempitsky who works in the same university as me and has a different view, which I do not agree but so what? It is his position.

[Ivan Oseledets @oseledetsivan]

@jatentaki @wellingmax Every day in Donbass there are military clashes and people die. OSCE mission reports: https://t.co/3or4oWug1R This can blow up at any time.
