Ranking Models in Unlabeled New Environments

2 code implementations ICCV 2021 Xiaoxiao Sun, Yunzhong Hou, Weijian Deng, Hongdong Li, Liang Zheng

For this problem, we propose to adopt a proxy dataset that 1) is fully labeled and 2) well reflects the true model rankings in a given target environment, and use the performance rankings on the proxy sets as surrogates.

Clinical Skin Lesion Diagnosis Using Representations Inspired by Dermatologist Criteria

no code implementations CVPR 2018 Jufeng Yang, Xiaoxiao Sun, Jie Liang, Paul L. Rosin

Accordingly, we design six medical representations considering different criteria for the recognition of skin lesions, and construct a diagnosis system for clinical skin disease images.
