Brief Introduction for Data-Efficient Deep Learning

Mitigating the requirement for labeled data is a vital issue in deep learning community. However, common practices of TL and SSL only focus on either the pre-trained model or unlabeled data. This paper unleashes the power of both worlds by proposing a new setup named data-efficient deep learning, aims to mitigate the requirement of labeled data by unifying the exploration of labeled and unlabeled data and the transfer of pre-trained model.

To address the challenge of confirmation bias in self-training, a general Pseudo Group Contrast mechanism is devised to mitigate the reliance on pseudo-labels and boost the tolerance to false labels. To tackle the model shift problem, we unify the exploration of labeled and unlabeled data and the transfer of a pre-trained model, with a shared key queue beyond just 'parallel training'. Comprehensive experiments demonstrate that Self-Tuning outperforms its SSL and TL counterparts on five tasks by sharp margins, e.g., it doubles the accuracy of fine-tuning on Stanford-Cars provided with 15% labels.
