Optimal Parameter-Free Second-order Acceleration with Inexact Hessians under Generalized Smoothness
Artem Agafonov, Aslan Ashabokov, Alexander D'yakonov +3
We study second-order convex optimization under generalized Hessian smoothness, where the local Hessian Lipschitz constant may grow linearly with the gradient norm. For inexact Hes…
Smooth or Separable? Sparse Block Acceleration for Entropy-Regularized Linear Programs
Irina Podlipnova, Maxim Mashtaler, Artem Agafonov +2
We study entropy-regularized linear programs with sparse affine constraints and compare two exact dual representations induced by whether a redundant normalization constraint is re…
Application of Optimal Inexact Second-Order Acceleration to Distributed Stochastic Optimization under Statistical Similarity
Yury A. Sokolov, Maxim K. Mashtaler, Alexander V. Gasnikov +3
We consider distributed stochastic convex optimization with a fixed budget of independent samples split among workers. Sample average approximation reduces the problem to a…
