Stronger Lower Bounds for (Non-)Anytime Acceleration of Gradient Descent

Minchan Jung, Hanseul Cho, Chulhee Yun

The rate-optimal convergence rate of gradient descent (GD) with a fixed step-size is well known to be $Θ (N^{- 1})$ for $L$ -Lipschitz smooth convex objectives in the prior art in con…

Data-Constrained Language Model Pretraining: Improved Regularization and Scaling Laws

Zhiwei Xu, Shihao Wu, Hanseul Cho +2

Classical scaling laws for language model pretraining balance model size against training dataset size under a fixed compute budget, assuming abundant data and a single pass over t…
