Spatiotemporal Self-attention Modeling with Temporal Patch Shift for Action Recognition

1 code implementation27 Jul 2022 Wangmeng Xiang, Chao Li, Biao Wang, Xihan Wei, Xian-Sheng Hua, Lei Zhang

For 3D video-based tasks such as action recognition, however, directly applying spatiotemporal transformers on video data will bring heavy computation and memory burdens due to the largely increased number of patches and the quadratic complexity of self-attention computation.

SP-ViT: Learning 2D Spatial Priors for Vision Transformers

1 code implementation15 Jun 2022 Yuxuan Zhou, Wangmeng Xiang, Chao Li, Biao Wang, Xihan Wei, Lei Zhang, Margret Keuper, Xiansheng Hua

Unlike convolutional inductive biases, which are forced to focus exclusively on hard-coded local regions, our proposed SPs are learned by the model itself and take a variety of spatial relations into account.

Interactive Self-Training With Mean Teachers for Semi-Supervised Object Detection

no code implementations CVPR 2021 Qize Yang, Xihan Wei, Biao Wang, Xian-Sheng Hua, Lei Zhang

Specifically, to alleviate the instability among the detection results in different iterations, we propose using nonmaximum suppression to fuse the detection results from different iterations.

Continual Local Replacement for Few-shot Learning

no code implementations23 Jan 2020 Canyu Le, Zhonggui Chen, Xihan Wei, Biao Wang, Lei Zhang

The goal of few-shot learning is to learn a model that can recognize novel classes based on one or few training data.

Learning Continually from Low-shot Data Stream

no code implementations27 Aug 2019 Canyu Le, Xihan Wei, Biao Wang, Lei Zhang, Zhonggui Chen

To solve these two limits, the deep learning model should not only be able to learn from a few of data, but also incrementally learn new concepts from data stream over time without forgetting the previous knowledge.
