Noise Is Also Useful: Negative Correlation-Steered Latent Contrastive Learning

no code implementations CVPR 2022 Jiexi Yan, Lei Luo, Chenghao Xu, Cheng Deng, Heng Huang

While in metric space, we utilize weakly-supervised contrastive learning to excavate these negative correlations hidden in noisy data.

Domain-Smoothing Network for Zero-Shot Sketch-Based Image Retrieval

1 code implementation22 Jun 2021 Zhipeng Wang, Hao Wang, Jiexi Yan, Aming Wu, Cheng Deng

Most existing methods regard ZS-SBIR as a traditional classification problem and employ a cross-entropy or triplet-based loss to achieve retrieval, which neglect the problems of the domain gap between sketches and natural images and the large intra-class diversity in sketches.
