Geometric Prior Guided Feature Representation Learning for Long-Tailed Classification

no code implementations21 Jan 2024 Yanbiao Ma, Licheng Jiao, Fang Liu, Shuyuan Yang, Xu Liu, Puhua Chen

In this work, we propose to leverage the geometric information of the feature distribution of the well-represented head class to guide the model to learn the underlying distribution of the tail class.
