WebMar 20, 2024 · The cycle consists of seven main steps: 1. Clarify learning targets. Start with the broad learning goal of a unit of study, such as: Students will use multiple sources to analyze a topic in order to develop and present an evidence-based argument. WebSelf-supervised contrastive methods [16, 6] belong to this category. In this work, we use a GAN as a novel view gen-erator for contrastive learning, which does not require a la-beled source dataset. Here, we aim at enhancing view diversity for contrastive learning via generation under the fully unsupervised set-ting.
