Geometric Prior Guided Feature Representation Learning for Long-Tailed Classification

2 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.

Predicting and Enhancing the Fairness of DNNs with the Curvature of Perceptual Manifolds

2 code implementations CVPR 2023 Yanbiao Ma, Licheng Jiao, Fang Liu, Maoji Wen, Lingling Li, Wenping Ma, Shuyuan Yang, Xu Liu, Puhua Chen

To address the challenges of long-tailed classification, researchers have proposed several approaches to reduce model bias, most of which assume that classes with few samples are weak classes.
