Invertible Diffusion Models for Compressed Sensing

no code implementations25 Mar 2024 Bin Chen, Zhenyu Zhang, Weiqi Li, Chen Zhao, Jiwen Yu, Shijie Zhao, Jie Chen, Jian Zhang

To enable such memory-intensive end-to-end finetuning, we propose a novel two-level invertible design to transform both (1) the multi-step sampling process and (2) the noise estimation U-Net in each step into invertible networks.

Long-Tailed Learning as Multi-Objective Optimization

no code implementations31 Oct 2023 Weiqi Li, Fan Lyu, Fanhua Shang, Liang Wan, Wei Feng

Real-world data is extremely imbalanced and presents a long-tailed distribution, resulting in models that are biased towards classes with sufficient samples and perform poorly on rare classes.

OPDN: Omnidirectional Position-aware Deformable Network for Omnidirectional Image Super-Resolution

no code implementations26 Apr 2023 Xiaopeng Sun, Weiqi Li, Zhenyu Zhang, Qiufang Ma, Xuhan Sheng, Ming Cheng, Haoyu Ma, Shijie Zhao, Jian Zhang, Junlin Li, Li Zhang

Model A aims to enhance the feature extraction ability of 360{\deg} image positional information, while Model B further focuses on the high-frequency information of 360{\deg} images.
