Investigating and Mitigating the Multimodal Hallucination Snowballing in Large Vision-Language Models

1 code implementation30 Jun 2024 Weihong Zhong, Xiaocheng Feng, Liang Zhao, Qiming Li, Lei Huang, Yuxuan Gu, Weitao Ma, Yuan Xu, Bing Qin

To mitigate this, we further propose a training-free method called Residual Visual Decoding, where we revise the output distribution of LVLMs with the one derived from the residual visual input, providing models with direct access to the visual information.

CCML: Curriculum and Contrastive Learning Enhanced Meta-Learner for Personalized Spatial Trajectory Prediction

no code implementations journal 2024 Jing Zhao, Jiajie Xu, Yuan Xu, Junhua Fang, Pingfu Chao and Xiaofang Zhou

Moreover, these methods do not explicitly consider the diversity of moving patterns among users and trajectories, i. e., the learning difficulty of different user and trajectory samples, thus hindering the improvement of prediction accuracy.

Probing Synergistic High-Order Interaction in Infrared and Visible Image Fusion

1 code implementation CVPR 2024 Naishan Zheng, Man Zhou, Jie Huang, JunMing Hou, Haoying Li, Yuan Xu, Feng Zhao

To bridge this gap we introduce a Synergistic High-order Interaction Paradigm (SHIP) designed to systematically investigate spatial fine-grained and global statistics collaborations between infrared and visible images across two fundamental dimensions: 1) Spatial dimension: we construct spatial fine-grained interactions through element-wise multiplication mathematically equivalent to global interactions and then foster high-order formats by iteratively aggregating and evolving complementary information enhancing both efficiency and flexibility.

Omnipotent Adversarial Training in the Wild

1 code implementation14 Jul 2023 Guanlin Li, Kangjie Chen, Yuan Xu, Han Qiu, Tianwei Zhang

We first introduce an oracle into the adversarial training process to help the model learn a correct data-label conditional distribution.

Mixed noise reduction via sparse error constraint representation of high frequency image for wildlife image

1 code implementation Multimedia Tools and Applications 2022 Yuan Xu, Yaqin Zhao, Peng Lu

Wildlife image noise reduction is a difficult and challenging problem since the images are inevitably corrupted by the mixed noise in the complex field environments.
