DocOS: A Benchmark for Proactive Document-Guided Actions in GUI Agents

ICML 2026poster

While Graphical User Interface (GUI) agents have shown promising performance in automated device interaction, they primarily depend on static parametric knowledge from pre-training or instruction tuning. This reliance fundamentally limits their ability to handle long-tailed tasks that require explic…

Efficient Diffusion Models via Time Step Optimization with Consistent Training and Inference Constraints

ICML 2026poster

Diffusion probabilistic models (DPMs)’ sampling process is often inefficient, requiring hundreds to thousands of iterative steps to accurately approximate the diffusion trajectory. This inefficiency limits their practical applicability. Although recent advances in sampling efficiency—such as numeric…

Compress Large Language Models via Collaboration Between Learning and Matrix Approximation

NeurIPS 2025poster

Sparse and low-rank matrix composite approximation has emerged as a promising paradigm for compressing large language models (LLMs), offering a more flexible pruning structure than conventional methods based solely on sparse matrices. The significant variation in weight redundancy across layers, alo…

Efficient Representativeness-Aware Coreset Selection

NeurIPS 2025poster

Dynamic coreset selection is a promising approach for improving the training efficiency of deep neural networks by periodically selecting a small subset of the most representative or informative samples, thereby avoiding the need to train on the entire dataset. However, it remains inherently challen…

RepoDebug: Repository-Level Multi-Task and Multi-Language Debugging Evaluation of Large Language Models

EMNLP 2025

Large Language Models (LLMs) have exhibited significant proficiency in code debugging, especially in automatic program repair, which may substantially reduce the time consumption of developers and enhance their efficiency. Significant advancements in debugging datasets have been made to promote the

ToolSpectrum: Towards Personalized Tool Utilization for Large Language Models

ACL 2025finding

While integrating external tools into large language models (LLMs) enhances their ability to access real-time information and domain-specific services, existing approaches focus narrowly on functional tool selection following user instructions while overlooking the critical role of context-aware per…
