Memory-Efficient Backpropagation through Large Linear Layers

2 code implementations31 Jan 2022 Daniel Bershatsky, Aleksandr Mikhalev, Alexandr Katrutsa, Julia Gusak, Daniil Merkulov, Ivan Oseledets

Also, we investigate the variance of the gradient estimate induced by the randomized matrix multiplication.

Meta-Solver for Neural Ordinary Differential Equations

1 code implementation15 Mar 2021 Julia Gusak, Alexandr Katrutsa, Talgat Daulbaev, Andrzej Cichocki, Ivan Oseledets

Moreover, we show that the right choice of solver parameterization can significantly affect neural ODEs models in terms of robustness to adversarial attacks.

Preconditioning Kaczmarz method by sketching

1 code implementation5 Mar 2019 Alexandr Katrutsa, Ivan Oseledets

Therefore, to reduce this complexity, we use random sketching and compare it with the Kaczmarz method without preconditioning.
