S-learning: a joint supervised and self-supervised approach for robust learning with noisy labels

Noisy labels, resulting from manual labeling errors or unreliable data sources, can lead to overfitting and reduced generalization performance in neural networks when used for direct training. Self-supervised learning, which operates independently of labels, can mitigate the negative effects of noisy labels. Inspired by joint training that combines supervised and self-supervised learning, we propose an efficient method named S-learning for dealing with noisy labels. This method dynamically generates a clean sample set for supervised learning via three selection strategies: small-loss selection within class, high-confidence selection, and high-similarity selection. Meanwhile, other samples are utilized for self-supervised learning. Comprehensive experiments conducted on both synthetic and real-world noisy datasets show that S-learning surpasses numerous state-of-the-art methods.

Abstract

Noisy labels, resulting from manual labeling errors or unreliable data sources, can lead to overfitting and reduced generalization performance in neural networks when used for direct training. Self-supervised learning, which operates independently of labels, can mitigate the negative effects of noisy labels. Inspired by joint training that combines supervised and self-supervised learning, we propose an efficient method named S-learning for dealing with noisy labels. This method dynamically generates a clean sample set for supervised learning via three selection strategies: small-loss selection within class, high-confidence selection, and high-similarity selection. Meanwhile, other samples are utilized for self-supervised learning. Comprehensive experiments conducted on both synthetic and real-world noisy datasets show that S-learning surpasses numerous state-of-the-art methods.
