WebSelf-supervised contrastive methods [16, 6] belong to this category. In this work, we use a GAN as a novel view gen-erator for contrastive learning, which does not require a la-beled source dataset. Here, we aim at enhancing view diversity for contrastive learning via generation under the fully unsupervised set-ting. WebApr 12, 2024 · We show that learning order largely corresponds to label accuracy–early-learned silver labels have, on average, more accurate labels than later-learned silver labels. Then, during pre-training, we increase the weights of accurate labels within a novel contrastive learning objective.
