An empirical study of domain-agnostic semi-supervised learning via energy-based models: joint-training and pre-training

no code implementations25 Oct 2020 Yunfu Song, Huahuan Zheng, Zhijian Ou

In contrast, generative SSL methods involve unsupervised learning based on generative models by either joint-training or pre-training, and are more appealing from the perspective of being domain-agnostic, since they do not inherently require data augmentations.
