Proposed evidential deep active learning approach for semi-supervised classification (EDALSSC) focuses on uncertainty estimation of prediction results during the learning process.
EDALSSC builds a framework to quantify uncertainty estimation of labeled and unlabeled data simultaneously using evidential deep learning.
The uncertainty estimation of labeled data involves evidential deep learning, while that of unlabeled data is modeled by combining ignorance and conflict information of evidence.
Experimental results show that EDALSSC outperforms existing semi-supervised and supervised active learning approaches on image classification datasets.
