Reliability and Effectiveness of Autonomous AI Agents in Supply Chain Management

It is shown that this instability can propagate across echelons and compound over time, even when the underlying demand path is held fixed, and two approaches for improving reliability are evaluated: reinforcement-learning post-training and operational guardrails.

Variance-Reduced Q-Learning over Static and Time-Varying Networks

It is proved that such speedups in sample-complexity require only $\tilde O\left( 1 \right)$ communication, substantially improving upon the communication costs in prior work.

High-Probability Convergence of SGD via Batched Updates

This work proposes Batched SGD, a simple variant that partitions online samples into epochs and performs a single update per epoch using a refined, low-variance gradient estimate, and provides the first high-probability guarantees for FL.
