• CSI: Novelty Detection via Contrastive Learning on Distributionally Shifted Instances
  • Training scheme contrasts the sample with distributionally-shifted augmentations of itself.
  • Model learns a new task of discriminating between in- and out-of-distribution, in addition to the original task of discriminating within in-distribution.

• Maximum Mean Discrepancy, MMD 最大均值差异
  • 求两个概率分布映射到另一个空间中的数据的均值之差。
• 度量学习
  • 核心是聚类假设：同一簇数据极有可能属于同一级别。度量学习着重刻画样本与样本间的距离。度量学习对于类内距、类间距的学习更加重视。
