Splet29. jun. 2024 · Semi-supervised learning (SSL) has been a powerful strategy to incorporate few labels in learning better representations. In this paper, we focus on a practical scenario that one aims to apply SSL when unlabeled data may contain out-of-class samples - those that cannot have one-hot encoded labels from a closed-set of classes in label data, i.e SpletThe cross-entropy loss has been the default in deep learning for the last few years for supervised learning. This paper proposes a new loss, the supervised c...
