Web(a) The contrastive strategy of self-supervised contrastive learning. (b) Our group-aware contrastive strategy. The sample with a 30 age label and in a blue box is the anchor image. Samples within the same age group as the anchor, also including the augmentation view of the anchor framed by a red box, form positive pairs (top row) with the anchor.

WebABSTRACT. Recently, contrastive learning (CL) has emerged as a successful method for unsupervised graph representation learning. Most graph CL methods first perform stochastic augmentation on the input graph to obtain two graph views and maximize the agreement of representations in the two views. Despite the prosperous development of … WebApr 19, 2024 · In supervised contrastive learning, the representations of points from the same class (e.g., of two dogs) are pulled together, while representations from different classes are pushed apart (e.g., dog and elephant). ...
