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.

Representation Learning

Data-Centric Long-Tailed Image Recognition

no code implementations3 Nov 2023 Yanbiao Ma, Licheng Jiao, Fang Liu, Shuyuan Yang, Xu Liu, Puhua Chen

In the context of the long-tail scenario, models exhibit a strong demand for high-quality data.

Orthogonal Uncertainty Representation of Data Manifold for Robust Long-Tailed Learning

no code implementations16 Oct 2023 Yanbiao Ma, Licheng Jiao, Fang Liu, Shuyuan Yang, Xu Liu, Lingling Li

The disadvantage is that these methods generally pursue models with balanced class accuracy on the data manifold, while ignoring the ability of the model to resist interference.

Action Spotting Camera Calibration +4

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.

Delving into Semantic Scale Imbalance

no code implementations30 Dec 2022 Yanbiao Ma, Licheng Jiao, Fang Liu, Yuxin Li, Shuyuan Yang, Xu Liu

Due to the prevalence of semantic scale imbalance, we propose semantic-scale-balanced learning, including a general loss improvement scheme and a dynamic re-weighting training framework that overcomes the challenge of calculating semantic scales in real-time during iterations.
