Instance level contrastive learning

Nettet15. apr. 2024 · Contrastive learning module is introduced into our network to exploit more common semantics information and HSIC constraint can effectively exploit the complementary information from multiple-view data, in which \(v^{th}\) high level semantic representation \(H^v\) is obtained for constructing contrastive loss. Nettet28. jun. 2024 · In addition, the task-level and instance-level overfitting problems in few-shot text classification caused by a few training examples are not sufficiently tackled. In this work, we propose a contrastive learning framework named ContrastNet to tackle both discriminative representation and overfitting problems in few-shot text classification.
