Training-Free Unsupervised Prompt for Vision-Language Models

1 code implementation25 Apr 2024 Sifan Long, Linbin Wang, Zhen Zhao, Zichang Tan, Yiming Wu, Shengsheng Wang, Jingdong Wang

In light of this, we propose Training-Free Unsupervised Prompts (TFUP), which maximally preserves the inherent representation capabilities and enhances them with a residual connection to similarity-based prediction probabilities in a training-free and labeling-free manner.

HAP: Structure-Aware Masked Image Modeling for Human-Centric Perception

1 code implementation NeurIPS 2023 Junkun Yuan, Xinyu Zhang, Hao Zhou, Jian Wang, Zhongwei Qiu, Zhiyin Shao, Shaofeng Zhang, Sifan Long, Kun Kuang, Kun Yao, Junyu Han, Errui Ding, Lanfen Lin, Fei Wu, Jingdong Wang

To further capture human characteristics, we propose a structure-invariant alignment loss that enforces different masked views, guided by the human part prior, to be closely aligned for the same image.

Augmentation Matters: A Simple-yet-Effective Approach to Semi-supervised Semantic Segmentation

1 code implementation CVPR 2023 Zhen Zhao, Lihe Yang, Sifan Long, Jimin Pi, Luping Zhou, Jingdong Wang

Differently, in this work, we follow a standard teacher-student framework and propose AugSeg, a simple and clean approach that focuses mainly on data perturbations to boost the SSS performance.

Instance-specific and Model-adaptive Supervision for Semi-supervised Semantic Segmentation

1 code implementation CVPR 2023 Zhen Zhao, Sifan Long, Jimin Pi, Jingdong Wang, Luping Zhou

Relying on the model's performance, iMAS employs a class-weighted symmetric intersection-over-union to evaluate quantitative hardness of each unlabeled instance and supervises the training on unlabeled data in a model-adaptive manner.

Beyond Attentive Tokens: Incorporating Token Importance and Diversity for Efficient Vision Transformers

1 code implementation CVPR 2023 Sifan Long, Zhen Zhao, Jimin Pi, Shengsheng Wang, Jingdong Wang

In this paper, we emphasize the cruciality of diverse global semantics and propose an efficient token decoupling and merging method that can jointly consider the token importance and diversity for token pruning.
