Markovian Compression: Looking to the Past Helps Accelerate the Future

Andrey Veprikov, Vladimir Solodkin, Mikhail Rudakov +2

This paper deals with distributed optimization problems that use compressed communication to achieve efficient performance and mitigate communication bottleneck. We propose a famil…

DyKAF: Dynamical Kronecker Approximation of the Fisher Information Matrix for Gradient Preconditioning

Nikolay Yudin, Ekaterina Grishina, Andrey Veprikov +2

Recently, optimizers that explicitly treat weights as matrices, rather than flattened vectors, have demonstrated their effectiveness. This perspective naturally leads to structured…

Aligning Distributionally Robust Optimization with Practical Deep Learning Needs

Dmitrii Feoktistov, Igor Ignashin, Andrey Veprikov +4

While traditional Deep Learning (DL) optimization methods treat all training samples equally, Distributionally Robust Optimization (DRO) adaptively assigns importance weights to di…

Faster Than SVD, Smarter Than SGD: The OPLoRA Alternating Update

Abdulla Jasem Almansoori, Maria Ivanova, Andrey Veprikov +3

Low-Rank Adaptation (LoRA) fine-tunes large models by learning low-rank updates on top of frozen weights, dramatically reducing trainable parameters and memory. However, there is s…

Leveraging Coordinate Momentum in SignSGD and Muon: Memory-Optimized Zero-Order

Egor Petrov, Grigoriy Evseev, Aleksey Antonov +4

Fine-tuning Large Language Models (LLMs) is essential for adapting pre-trained models to downstream tasks. Yet traditional first-order optimizers such as Stochastic Gradient Descen…

WeightLoRA: Keep Only Necessary Adapters

Andrey Veprikov, Vladimir Solodkin, Alexander Zyl +2

The widespread utilization of language models in modern applications is inconceivable without Parameter-Efficient Fine-Tuning techniques, such as low-rank adaptation ($\texttt{LoRA…
