Novel contrastive representation learningとは
WebIn this paper, we propose a novel graph contrastive representation learning method with adaptive augmentation that incorporates various priors for topological and semantic aspects of the graph. Specifically, on the topology level, we design augmentation schemes based on node centrality measures to highlight important connective structures. WebApr 19, 2024 · Contrastive learning describes a set of techniques for training deep networks by comparing and contrasting the models' representations of data. The central idea in contrastive learning is to take the representation of a point, and pull it closer to the representations of some points (called positives) while pushing it apart from the ...
