FlexiGrad: Adaptive Gradient Modulation for Hierarchical Fine-Grained Classification

Zilu Zhou, Dongliang Chang, Junhan Chen, Zhanyu Ma

Many fine-grained recognition tasks contain hierarchical labels such as order, family and species. Although this supervision should be beneficial, jointly optimising all levels often leads to unstable training because coarse and fine classifiers impose inconsistent gradients on t…Read more
