WebMay 31, 2024 · The goal of contrastive representation learning is to learn such an embedding space in which similar sample pairs stay close to each other while dissimilar ones are far apart. Contrastive learning can be applied to both supervised and unsupervised settings. When working with unsupervised data, contrastive learning is one of the most … WebThe metric learning approach utilizes a Siamese neural network (SNN) architecture, which learns a PPGR embedding via a contrastive loss function adapted to the task of interest.
