arXiv:2606.26316v1 Announce Type: new Abstract: We study first-order methods for smooth objectives satisfying the Polyak-\L{}ojasiewicz (PL) condition when gradient samples are generated by an exogenous Markov chain. In the light-tailed setting, prior uniform-in-time high-probability bounds for ordinary Stochastic Gradient Descent (SGD) under a standard growth envelope scale as $\widetilde{O}(t_{mix}^2/k)$, leaving a gap with the $\widetilde{O}(t_{mix}/k)$ expectation bounds. We close this gap using a lag-blocking argument to establish a uniform high-probability guarantee with a leading stocha
Ongoing research in optimizing machine learning algorithms continues to refine their theoretical underpinnings and practical efficiency.
Improved theoretical guarantees for stochastic optimization methods can lead to more robust and efficient AI systems, especially in scenarios with noisy data.
This research provides tighter bounds for high-probability performance of SGD under specific noise conditions, closing a theoretical gap in distributed training and AI operations.
