On the Wings of Imagination: Conflicting Script-based Multi-role Framework for Humor Caption Generation

ICLR 2026poster

Humor is a commonly used and high-level human language in daily life. However, humor generation is a challenging task for large language models (LLMs) in multi-modal contexts, but with many useful applications of funny caption generation for images, requiring visual understanding, humor reasoning, c…

S2FT: Parameter-Efficient Fine-Tuning in Sparse Spectrum Domain

CVPR 2026

Parameter Efficient Fine-Tuning (PEFT) is a key technique for adapting a large pretrained model to downstream tasks by fine-tuning only a small number of parameters. Recent methods based on Fourier transforms have further reduced the fine-tuned parameters scale by only fine-tuning a few spectral coe

CausalAbstain: Enhancing Multilingual LLMs with Causal Reasoning for Trustworthy Abstention

ACL 2025finding

Large Language Models (LLMs) often exhibit knowledge disparities across languages. Encouraging LLMs to abstain when faced with knowledge gaps is a promising strategy to reduce hallucinations in multilingual settings. Current abstention strategies for multilingual scenarios primarily rely on generati…

SHARP: Unlocking Interactive Hallucination via Stance Transfer in Role-Playing LLMs

ACL 2025finding

The advanced role-playing capabilities of Large Language Models (LLMs) have enabled rich interactive scenarios, yet existing research in social interactions neglects hallucination while struggling with poor generalizability and implicit character fidelity judgments. To bridge this gap, motivated by…

Text-Tuple-Table: Towards Information Integration in Text-to-Table Generation via Global Tuple Extraction

EMNLP 2024main

The task of condensing large chunks of textual information into concise and structured tables has gained attention recently due to the emergence of Large Language Models (LLMs) and their potential benefit for downstream tasks, such as text summarization and text mining. Previous approaches often gen…
