Weasel: Out-of-Domain Generalization for Web Agents via Importance-Diversity Data Selection

ICML 2026poster

Large language models (LLMs) have enabled web agents that follow natural language goals through multi-step browser interactions. However, agents fine-tuned on specific trajectories and domain often struggle to generalize out of domain, and offline training can be compute-inefficient due to noisy, re…

LPOI: Listwise Preference Optimization for Vision Language Models

ACL 2025long

Aligning large VLMs with human preferences is a challenging task, as methods like RLHF and DPO often overfit to textual information or exacerbate hallucinations. Although augmenting negative image samples partially addresses these pitfalls, no prior work has employed listwise preference optimization…

Text2Chart31: Instruction Tuning for Chart Generation with Automatic Feedback

EMNLP 2024main

Large language models (LLMs) have demonstrated strong capabilities across various language tasks, notably through instruction-tuning methods. However, LLMs face challenges in visualizing complex, real-world data through charts and plots. Firstly, existing datasets rarely cover a full range of chart…

mRedditSum: A Multimodal Abstractive Summarization Dataset of Reddit Threads with Images

EMNLP 2023long main

The growing number of multimodal online discussions necessitates automatic summarization to save time and reduce content overload. However, existing summarization datasets are not suitable for this purpose, as they either do not cover discussions, multiple modalities, or both. To this end, we prese…
