    A new method of semi-supervised learning classification based on multi-mode augmentation in small labeled sample environment by Yuxuan Liu, Chenglin Wen

    Published 2025-07-01
    “…To this end, this paper proposes a semi-supervised image classification method based on multi-mode augmentation, which mitigates the effects of insufficient quality and limited scale of unlabeled data by simultaneously improving the sample completeness within and between classes. Specifically, the model’s prediction confidence and bias are used for uncertainty-based screening to improve pseudo-label quality, while retaining as many unlabeled samples as possible to fully exploit their potential information. …”
