DINO: Emerging Properties in Self-Supervised Vision Transformers (Facebook AI Research Explained)

#dino #facebook #selfsupervised Self-Supervised Learning is the final frontier in Representation Learning: Getting useful features without any labels. Facebook AI’s new system, DINO, combines advances in Self-Supervised Learning for Computer Vision with the new Vision Transformer (ViT) architecture and achieves impressive results without any labels. Attention maps can be directly interpreted as segmentation maps, and the obtained representations can be used for image retrieval and zero-shot k-nearest neighbor classifiers (KNNs).
