Webb3 juni 2024 · 在本文中，我们使用了对比学习（Contrastive Learning）来达到上述目的。 对比学习是目前被广泛应用的自监督任务之一，其核心思想为：人类是通过“对比”来辨别对象的，因此相似的事物在编码后的表示空间中应当相近，不同的事物则应当相距尽可能远。 通过对同一样本施加不同的数据增强方法，我们能够得到一系列“自相似”的文本对作为正 … WebbAlternatively to performing the validation on the contrastive learning loss as well, we could also take a simple, small downstream task, and track the performance of the base network on that. However, in this tutorial, we will restrict ourselves to the STL10 dataset where we use the task of image classification on STL10 as our test task.
Exploring Simple Siamese Representation Learning
Webb1) We propose a simple but effective sentence-level training objective based on contrastive learning. It mitigates the collapse of BERT-derived repre-sentations and transfers them to downstream tasks. 2) We explore various effective text augmentation strategies to generate views for contrastive learning and analyze their effects on unsupervised ...

SimCSE: Simple Contrastive Learning of Sentence Embeddings
WebbIn addition, these methods simply adopt the original framework of contrastive learning developed for image representation, which is not suitable for learning sentence embedding. To address these issues, we propose a method dubbed unsupervised contrastive learning of sentence embedding with prompt (CLSEP), aiming to provide … Webb3 juni 2024 · Contrastive learning is used for unsupervised pre-training in above discussions. Contrastive learning is to learn a metric space between two samples in which the distance between two... Webb4 maj 2024 · Improving Graph Collaborative Filtering with Neighborhood-enriched Contrastive Learning 对比学习可以缓解推荐系统中数据稀疏问题，图方法可以考虑邻域节点之间的关系，两者都对协同过滤有提升效果。 因此，图+对比学习是很合适的建模思路。 这篇文章提出NCL（Neighborhood-enriched Contrastive Learning）方法，主要从两方 … fixing split keypad on ipad
