How Accurate Is Accurate Enough?

Ningkang Peng, Qianfeng Yu, Jingyang Mao +2

How accurate must a numerical approximation be within a learning system? Primitive error alone cannot answer this question: errors of the same magnitude can have very different con…

Does a Shared Temperature Imply a Shared Angular Scale in Probabilistic Contrastive Learning?

Ningkang Peng, Qianfeng Yu, Jingyang Mao +4

In probabilistic contrastive learning, a shared temperature is commonly interpreted as a shared similarity scale, but this interpretation does not hold for high-dimensional distrib…

GAMR: Geometric-Aware Manifold Regularization with Virtual Outlier Synthesis for Learning with Noisy Labels

Ningkang Peng, Jingyang Mao, Xiaoqian Peng +4

Deep neural networks (DNNs) experience significant performance degradation when processing noisy labels, primarily due to overfitting on mislabeled data. Current mainstream approac…

Holistic Reliability Propagation: Decoupling Annotation and Prediction for Robust Noisy-Label

Jingyang Mao, Ningkang Peng, Yanhui Gu

Learning with noisy labels in multimedia classification often combines external annotations and model predictions into a single reliability weight, even though the two sources can…

When Accuracy Is Not Enough: Uncertainty Collapse between Noisy Label Learning and Out-of-Distribution Detection

Ningkang Peng, Jingyang Mao, Runhan Zhou +2

Learning with noisy labels (LNL) is typically benchmarked by closed-set classification accuracy, yet deployment often requires classifiers to reject out-of-distribution (OOD) input…

Radial-Angular Geometry for Reliable Update Diagnosis in Noisy-Label Learning

Ningkang Peng, Jingyang Mao, Xiaoqian Peng +2

Noisy-label methods often estimate sample reliability from forward-space signals such as loss, confidence, or entropy. These signals indicate whether a sample is difficult to predi…

HamBR: Active Decision Boundary Restoration Based on Hamiltonian Dynamics for Learning with Noisy Labels

Ningkang Peng, Jingyang Mao, Qianfeng Yu +3

In large-scale visual recognition and data mining tasks, the presence of noisy labels severely undermines the generalization capability of deep neural networks (DNNs). Prevalent sa…
