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.

Semi-Supervised Learning for Mars Imagery Classification and Segmentation

no code implementations5 Jun 2022 Wenjing Wang, Lilang Lin, Zejia Fan, Jiaying Liu

For segmentation, we extend supervised inter-class contrastive learning into an element-wise mode and use online pseudo labels for supervision on unlabeled areas.

Conditional DETR for Fast Training Convergence

3 code implementations ICCV 2021 Depu Meng, Xiaokang Chen, Zejia Fan, Gang Zeng, Houqiang Li, Yuhui Yuan, Lei Sun, Jingdong Wang

Our approach, named conditional DETR, learns a conditional spatial query from the decoder embedding for decoder multi-head cross-attention.

On the Connection between Local Attention and Dynamic Depth-wise Convolution

1 code implementation ICLR 2022 Qi Han, Zejia Fan, Qi Dai, Lei Sun, Ming-Ming Cheng, Jiaying Liu, Jingdong Wang

Sparse connectivity: there is no connection across channels, and each position is connected to the positions within a small local window.
