Towards Semi-Supervised Deep Facial Expression Recognition with An Adaptive Confidence Margin
Towards Semi-Supervised Deep Facial Expression Recognition with An Adaptive Confidence Margin
Only parts of unlabeled data are selected to train models for most semi-supervised learning methods, whose confidence scores are usually higher than the pre-defined threshold (i.e., the confidence margin). We argue that the recognition performance should be further improved by making full use of all unlabeled data. In this paper, …
