While collecting training data, even with the manual verification of experts from crowdsourcing platforms, eliminating incorrect annotations (noisy labels) completely is difficult and expensive. In dealing datasets that contain noisy labels, over-parameterized deep neural networks (DNNs) tend to overfit, leading poor generalization classification performance. As a result, label learning (NLL) has received significant attention in recent years. Existing research shows although DNNs eventually...
