Compositional Online Learning for Semantic Data Processing Systems

Paweł Liskowski, Fuheng Zhao, Benjamin Han +2

An LLM call in a semantic data processing system is expensive enough to dominate query cost, yet slow enough to hide a CPU-side learner's update behind its round-trip. In productio…

Finding the Right Tables and Columns: A Benchmark and Corpus-Adaptive Embeddings for SQL Schema Retrieval

Qingcheng Zeng, Puxuan Yu, Aman Mehta +2

Retrieval in the SQL setting has largely been studied as the task of finding, within a large collection of SQL statements, the statement that answers a natural-language question. A…

Beyond Monolingual Deep Research: Evaluating Agents and Retrievers with Cross-Lingual BrowseComp-Plus

Yuheng Lu, Qingcheng Zeng, Heli Qi +6

Deep research agents are increasingly evaluated on their ability to search for evidence, reason over retrieved sources, and produce grounded answers. Existing browsing benchmarks,…

Larch: Learned Query Optimization for Semantic Predicates

Fuheng Zhao, Pawel Liskowski, Zihan Li +5

With the advent of Large Language Models (LLMs), many database systems introduced semantic operators that enabled analytical queries over unstructured data (e.g. text, images, vide…

AvalancheBench: Evaluating Enterprise Data Agents Through Latent World Recovery

Darek Kleczek, Fuheng Zhao, Alexander W. Lee +4

We introduce AvalancheBench, a benchmark for evaluating enterprise data agents through \emph{latent world recovery}. AvalancheBench improves on existing benchmarks in three ways. F…

Dual-View Training for Instruction-Following Information Retrieval

Qingcheng Zeng, Puxuan Yu, Aman Mehta +2

Instruction-following information retrieval (IF-IR) studies retrieval systems that must not only find documents relevant to a query, but also obey explicit user constraints such as…

Code-Switching Information Retrieval: Benchmarks, Analysis, and the Limits of Current Retrievers

Qingcheng Zeng, Yuheng Lu, Zeqi Zhou +6

Code-switching is a pervasive linguistic phenomenon in global communication, yet modern information retrieval systems remain predominantly designed for, and evaluated within, monol…
