Contrastive training strategy

Webalize the paradigm of contrastive learning (Chopra et al.,2005) to introduce an approach for abstrac-tive summarization which achieves the goal of di-rectly optimizing the model with the correspond-ing evaluation metrics, thereby mitigating the gaps between training and test stages in MLE training. While some related work (Lee et al.,2024;Pan Weblearn better representations. For contrastive loss, we care-fully curate mini-batches by sampling various types of neg-atives and positives given a reference sample. We show the efficacy of our training paradigm across two rephrasing (i.e., data-augmentation) strategies. Using rephrasings obtained from a VQG model proposed in [44],
