MoCO

  • Momentum Contrast for Unsupervised Visual Representation Learning
  • unsupervised visual representation learning
  • contrastive learning as dictionary look-up, MoCo builds a dynamic dictionary with a queue and a moving-averaged encoder
  • large and consistent dictionary on-the-fly
  • ImageNet
  • transfer well to downstream tasks.
  • PASCAL VOC
  • COCO
  • visual representation encoder by matching an encoded query
  • to a dictionary of encoded keys using a Contrastive Loss
  • dictionary is built as a queue, with the current mini-batch enqueued
  • oldest mini-batch dequeued
  • slowly progressing encoder
  • momentum update with the query encoder
