A Queueing-Theoretic Framework for Stability Analysis of LLM Inference with KV Cache Memory Constraints

Chengyi Nie, Nian Si, Zijie Zhou

The rapid adoption of large language models (LLMs) has created significant challenges for efficient inference at scale. Unlike traditional workloads, LLM inference is constrained b…

Learning Optimal Distributionally Robust Stochastic Control in Continuous State Spaces

Shengbo Wang, Jason Meng, Nian Si +2

We study data-driven learning of robust stochastic control for infinite-horizon systems with potentially continuous state and action spaces. In many managerial settings--supply cha…

Selecting the Best Optimizing System

Nian Si, Yifu Tang, Zeyu Zheng

We formulate selecting the best optimizing system (SBOS) problems and provide solutions for those problems. In an SBOS problem, a finite number of systems are contenders. Inside ea…

On the Foundation of Distributionally Robust Reinforcement Learning

Shengbo Wang, Nian Si, Jose Blanchet +1

Motivated by the need for a robust policy in the face of environment shifts between training and deployment, we contribute to the theoretical foundation of distributionally robust…

ScoreFusion: Fusing Score-based Generative Models via Kullback-Leibler Barycenters

Hao Liu, Junze Tony Ye, Jose Blanchet +1

We introduce ScoreFusion, a theoretically grounded method for fusing multiple pre-trained diffusion models that are assumed to generate from auxiliary populations. ScoreFusion is p…
