WebJan 1, 2024 · We plug our strong augmentation into the unlabeled branches of two state-of-the-art consistency-based semi-supervised learning frameworks, FixMatch (Sohn et al., 2024) and UDA (Xie et al., 2024). In Table 2 (f), the two semi-supervised learning frameworks with per-frame augmentation are denoted as vanilla.
