WebJan 16, 2024 · Self-supervised learning aims to understand vital features using the raw input, which is helpful since labeled data is scarce and expensive. For the contrastive loss-based pre-training, data augmentation is applied to the dataset, and positive and negative instance pairs are fed into a deep learning model for feature learning.
WebFigure 2: Supervised vs. self-supervised contrastive losses: The self-supervised contrastive loss (left, Eq.1) contrasts a single positive for each anchor (i.e., an augmented version of the same image) against a set of negatives consisting of the entire remainder of the batch.
