10/16	Lecture #16 ( Runyu Zhang (Harvard) ): (Zoom link: https://gatech.zoom.us/j/93227128162) Scalable Distributed Control and Reinforcement Learning for Multi-Agent Network Systems [ recording (Canvas) ]	Multi-agent network systems play a critical role in modern societal infrastructures, including smart cities, power grids, and transportation networks. This talk will explore scalable distributed control and reinforcement learning (RL) techniques tailored for such systems. In the first part, I will focus on distributed control for networks with linear dynamics, demonstrating that under certain locality assumptions, distributed controllers can achieve near-global-optimal performance. Building upon this insight, the second part will extend to systems with potentially nonlinear dynamics. By leveraging representation learning, we approximate the dynamics as a linear combination of features, and introduce an algorithm that harnesses the network structure to ensure both convergence guarantees and strong empirical performance.

His research focuses on efficient generative modeling for text, image and structured data, and the corresponding fundamental algorithms in sampling and optimization. His research outcome has been adopted in OSS projects and launched in Google Workspace, Gemini and Cloud AI. His work has been recognized by the 2022 Google Research tech impact award, AISTATS 2016 best student paper and best workshop papers in Recsys and Neurips. He has also served as the Area Chair in top-tier conferences including AAAI, ICML, NeurIPS, co-organized workshops and tutorials in ICML, NeurIPS, LoG.): (Zoom link: https://gatech.zoom.us/j/95094662178) Universal Query Engine [ recording (Canvas) ]	Analytics on structured data is a mature field with many successful methods. However, most real world data exists in unstructured form, such as images and conversations. We investigate the potential of Large Language Models (LLMs) to enable unstructured data analytics. In particular, we propose a new Universal Query Engine (UQE) that directly interrogates and draws insights from unstructured data collections. This engine accepts queries in a Universal Query Language (UQL), a dialect of SQL that provides full natural language flexibility in specifying conditions and operators. The new engine leverages the ability of LLMs to conduct analysis of unstructured data, while also allowing us to exploit advances in sampling and optimization techniques to achieve efficient and accurate query execution. In addition, we borrow techniques from classical compiler theory to better orchestrate the workflow between sampling methods and foundation model calls. We demonstrate the efficiency of UQE on data analytics across different modalities, including images, dialogs and reviews, across a range of useful query types, including complex search that requires deep reasoning, or the aggregated summaries that would usually require massive human efforts.
