SPNet: A novel deep neural network for retinal vessel segmentation based on shared decoder and pyramid-like loss

no code implementations19 Feb 2022 Geng-Xin Xu, Chuan-Xian Ren

Also, to strengthen characterization on the capillaries and the edges of blood vessels, we define a residual pyramid architecture which decomposes the spatial information in the decoding phase.

Learning Target Domain Specific Classifier for Partial Domain Adaptation

no code implementations25 Aug 2020 Chuan-Xian Ren, PengFei Ge, Peiyi Yang, Shuicheng Yan

Previous UDA methods assume that the source and target domains share an identical label space, which is unrealistic in practice since the label information of the target domain is agnostic.

Learning Kernel for Conditional Moment-Matching Discrepancy-based Image Classification

no code implementations24 Aug 2020 Chuan-Xian Ren, PengFei Ge, Dao-Qing Dai, Hong Yan

KLN can simultaneously learn a more expressive kernel and label prediction distribution, thus, it can be used to improve the classification performance in both supervised and semi-supervised learning scenarios.

Domain Adaptive Person Re-Identification via Camera Style Generation and Label Propagation

no code implementations14 May 2019 Chuan-Xian Ren, Bo-Hua Liang, Zhen Lei

We derive a camera style adaptation framework to learn the style-based mappings between different camera views, from the target domain to the source domain, and then we can transfer the identity-based distribution from the source domain to the target domain on the camera level.
