NoLan: Mitigating Object Hallucinations in Large Vision-Language Models via Dynamic Suppression of Language Priors

Lingfeng Ren, Weihao Yu, Runpeng Yu +1

Object hallucination is a critical issue in Large Vision-Language Models (LVLMs), where outputs include objects that do not appear in the input image. A natural question arises fro…

Dimple: Discrete Diffusion Multimodal Large Language Model with Parallel Decoding

Runpeng Yu, Xinyin Ma, Xinchao Wang

In this work, we propose Dimple, the first Discrete Diffusion Multimodal Large Language Model (DMLLM). We observe that training with a purely discrete diffusion approach leads to s…

Encapsulating Knowledge in One Prompt

Qi Li, Runpeng Yu, Xinchao Wang

This paradigm encapsulates knowledge from various models into a solitary prompt without altering the original models or requiring access to the training data, which enables us to a…
