HARP: Efficient Data Selection for Finetuning Large Language Models

Ning Wang, Zhengxin Zhang, Maosen Tang +3

Finetuning data selection requires balancing two competing goals: selecting examples that improve the downstream objective, and doing so without repeatedly finetuning models. Train…

How Far Are We From True Auto-Research?

Zhengxin Zhang, Ning Wang, Sainyam Galhotra +1

Recent auto-research systems can produce complete papers, but feasibility is not the same as quality, and the field still lacks a systematic study of how good agent-generated paper…

Trace-Level Analysis of Information Contamination in Multi-Agent Systems

Anna Mazhar, Huzaifa Suri, Sainyam Galhotra

Reasoning over heterogeneous artifacts (PDFs, spreadsheets, slide decks, etc.) increasingly occurs within structured agent workflows that iteratively extract, transform, and refere…

Debugging Concept Bottleneck Models through Removal and Retraining

Eric Enouen, Sainyam Galhotra

Concept Bottleneck Models (CBMs) use a set of human-interpretable concepts to predict the final task label, enabling domain experts to not only validate the CBM's predictions, but…

Pruning Minimal Reasoning Graphs for Efficient Retrieval-Augmented Generation

Ning Wang, Kuanyan Zhu, Daniel Yuehwoon Yee +4

Retrieval-augmented generation (RAG) is now standard for knowledge-intensive LLM tasks, but most systems still treat every query as fresh, repeatedly re-retrieving long passages an…
