MATCH: Model-Aware Tool Learning with Curriculum Scheduling and Hierarchically Gated Rewards

Shihao Liu, Hao Yin, Lijun Liu +3

Tool learning enables large language models (LLMs) to use external tools for tasks beyond parametric knowledge. Reinforcement learning can optimize tool-call behavior from feedback…

Can LLM Annotations Replace User Clicks for Learning to Rank?

Lulu Yu, Keping Bi, Jiafeng Guo +4

Large-scale supervised data is essential for training modern ranking models, but obtaining high-quality human annotations is costly. Click data has been widely used as a low-cost a…

Utility-Focused LLM Annotation for Retrieval and Retrieval-Augmented Generation

Hengran Zhang, Minghao Tang, Keping Bi +5

This paper explores the use of large language models (LLMs) for annotating document utility in training retrieval and retrieval-augmented generation (RAG) systems, aiming to reduce…

Bacon-Shor Board Games

M. Sohaib Alam, Jun Zen, Thomas R. Scruby

We identify a period-4 measurement schedule for the checks of the Bacon-Shor code that fully covers spacetime with constant-weight detectors, and is numerically observed to provide…

Unbiased Learning to Rank with Query-Level Click Propensity Estimation: Beyond Pointwise Observation and Relevance

Lulu Yu, Keping Bi, Jiafeng Guo +3

Most existing unbiased learning-to-rank (ULTR) approaches are based on the user examination hypothesis, which assumes that users will click a result only if it is both relevant and…

Generative Retrieval for Book search

Yubao Tang, Ruqing Zhang, Jiafeng Guo +5

In book search, relevant book information should be returned in response to a query. Books contain complex, multi-faceted information such as metadata, outlines, and main text, whe…

InverseCoder: Self-improving Instruction-Tuned Code LLMs with Inverse-Instruct

Yutong Wu, Di Huang, Wenxuan Shi +13

Recent advancements in open-source code large language models (LLMs) have been driven by fine-tuning on the data generated from powerful closed-source LLMs, which are expensive to…
