Fine-grained zero-shot recognition with metric rescaling.

2019 · arXiv (Cornell University)

We address the problem of learning fine-grained cross-modal representations. We propose an instance-based deep metric learning approach in joint visual and textual space. On top of that, we derive a metric rescaling approach that solves …

Unsupervised Learning of Dense Visual Representations

2020 · arXiv (Cornell University)

Contrastive self-supervised learning has emerged as a promising approach to unsupervised visual representation learning. In general, these methods learn global (image-level) representations that are invariant to different views (i.e., compositions of data augmentation) of the …
