Deep learning with noisy labels is practically challenging, as the capacity of deep models so high that they can totally memorize these sooner or later during training. Nonetheless, recent studies on memorization effects neural networks show would first training data clean and then those labels. Therefore in this paper, we propose a new paradigm called ''Co-teaching'' for combating Namely, train two simultaneously, let them teach each other given every mini-batch: firstly, network feeds...

Learning with noisy labels is one of the hottest problems in weakly-supervised learning. Based on memorization effects deep neural networks, training small-loss instances becomes very promising for handling labels. This fosters state-of-the-art approach "Co-teaching" that cross-trains two networks using trick. However, increase epochs, converge to a consensus and Co-teaching reduces self-training MentorNet. To tackle this issue, we propose robust learning paradigm called Co-teaching+, which...

From only positive (P) and unlabeled (U) data, a binary classifier could be trained with PU learning, in which the state of art is unbiased learning. However, if its model very flexible, empirical risks on training data will go negative, we suffer from serious overfitting. In this paper, propose non-negative risk estimator for learning: when getting minimized, it more robust against overfitting, thus are able to use flexible models (such as deep neural networks) given limited P data....
