PCCT: Progressive Class-Center Triplet Loss for Imbalanced Medical Image Classification

no code implementations11 Jul 2022 Kanghao Chen, Weixian Lei, Rong Zhang, Shen Zhao, Wei-Shi Zheng, Ruixuan Wang

For the class-center involved triplet loss, the positive and negative samples in each triplet are replaced by their corresponding class centers, which enforces data representations of the same class closer to the class center.
