NL2Repo-Bench: Towards Long-Horizon Repository Generation Evaluation of Coding Agents

ICML 2026poster

Recent advances in coding agents suggest rapid progress toward autonomous software development, yet existing benchmarks primarily evaluate short-horizon behaviors such as localized code generation, scaffolded completion, or repository repair, leaving it unclear whether agents can sustain coherent re…

Towards Personalized Deep Research: Benchmarks and Evaluations

ICLR 2026poster

Deep Research Agents (DRAs) can autonomously conduct complex investigations and generate comprehensive reports, demonstrating strong real-world potential. However, existing evaluations mostly rely on close-ended benchmarks, while open-ended deep research benchmarks remain scarce and typically neglec…

Model Selection for Off-policy Evaluation: New Algorithms and Experimental Protocol

NeurIPS 2025poster

Holdout validation and hyperparameter tuning from data is a long-standing problem in offline reinforcement learning (RL). A standard framework is to use off-policy evaluation (OPE) methods to evaluate and select the policies, but OPE either incurs exponential variance (e.g., importance sampling) or…

OAgents: An Empirical Study of Building Effective Agents

EMNLP 2025

Recently, Agentic AI has become an increasingly popular field of research. However, we argue that current practices on agent research are far from standard, rigorous scientific research, which makes it hard to conduct apples-to-apples comparisons among and against existing methods. As a result, it i

Can Generative Pre-trained Language Models Serve As Knowledge Bases for Closed-book QA?

ACL 2021long

Recent work has investigated the interesting question using pre-trained language models (PLMs) as knowledge bases for answering open questions. However, existing work is limited in using small benchmarks with high test-train overlaps. We construct a new dataset of closed-book QA using SQuAD, and inv…
