Prompted Contrast with Masked Motion Modeling: Towards Versatile 3D Action Representation Learning

no code implementations8 Aug 2023 Jiahang Zhang, Lilang Lin, Jiaying Liu

Moreover, combining these two paradigms in a naive manner leaves the synergy between them untapped and can lead to interference in training.

Actionlet-Dependent Contrastive Learning for Unsupervised Skeleton-Based Action Recognition

no code implementations CVPR 2023 Lilang Lin, Jiahang Zhang, Jiaying Liu

However, these methods treat the motion and static parts equally, and lack an adaptive design for different parts, which has a negative impact on the accuracy of action recognition.

Hierarchical Consistent Contrastive Learning for Skeleton-Based Action Recognition with Growing Augmentations

1 code implementation24 Nov 2022 Jiahang Zhang, Lilang Lin, Jiaying Liu

In this paper, we investigate the potential of adopting strong augmentations and propose a general hierarchical consistent contrastive learning framework (HiCLR) for skeleton-based action recognition.

S$^{5}$Mars: Semi-Supervised Learning for Mars Semantic Segmentation

no code implementations4 Jul 2022 Jiahang Zhang, Lilang Lin, Zejia Fan, Wenjing Wang, Jiaying Liu

We first present a newdataset S5Mars for Semi-SuperviSed learning on Mars Semantic Segmentation, which contains 6K high-resolution images and is sparsely annotated based on confidence, ensuring the high quality of labels.
