Unveiling the Potential of Diffusion Large Language Model in Controllable Generation

ICLR 2026poster

Controllable generation is a fundamental task in NLP with many applications, providing a basis for function calling to agentic communication. However, even state-of-the-art autoregressive Large Language Models (LLMs) today exhibit unreliability when required to generate structured output. Inspired b…

DRS: Deep Question Reformulation With Structured Output

ACL 2025finding

Question answering represents a core capability of large language models (LLMs). However, when individuals encounter unfamiliar knowledge in texts, they often formulate questions that the text itself cannot answer due to insufficient understanding of the underlying information. Recent studies reveal…

Who is in the Spotlight: The Hidden Bias Undermining Multimodal Retrieval-Augmented Generation

EMNLP 2025

Multimodal Retrieval-Augmented Generation (RAG) systems have become essential in knowledge-intensive and open-domain tasks. As retrieval complexity increases, ensuring the robustness of these systems is critical. However, current RAG models are highly sensitive to the order in which evidence is pres
