Dual contrastive learning

Webples. Thus, we argue that the supervised contrastive learning developed so far appears to be a naive adaptation of unsuper-vised contrastive learning to the classification … WebWe formulate this intuition into a new learning framework that consists of two components, a social contrastive loss and a negative sampling strategy.. Given a scenario that contains a primary agent of interest (blue) and multiple neighboring agents in the vicinity (gray), our Social-NCE loss encourages the extracted motion representation, in an embedding …

WebJan 21, 2024 · In this work, we introduce a dual contrastive learning (DualCL) framework that simultaneously learns the features of input samples and the parameters of classifiers in the same space. Specifically, DualCL regards the parameters of the classifiers as augmented samples associating to different labels and then exploits the contrastive … WebIn this paper, inspired by previous works on contrastive learning [2, 7], we propose a dual contrastive method for unsupervised knowledge selection. From contrastive learn-ing, the model benefits from the contrast between positive samples and negative samples.
