Long-tailed Recognition by Routing Diverse Distribution-Aware Experts

ICLR 2021spotlight

Natural data are often long-tail distributed over semantic classes. Existing recognition methods tackle this imbalanced classification by placing more emphasis on the tail data, through class re-balancing/re-weighting or ensembling over different data groups, resulting in increased tail accuracies…

The Emergence of Objectness: Learning Zero-shot Segmentation from Videos

NeurIPS 2021poster

Humans can easily detect and segment moving objects simply by observing how they move, even without knowledge of object semantics. Inspired by this, we develop a zero-shot unsupervised approach for learning object segmentations. The model comprises two visual pathways: an appearance pathway that seg…

Universal Weakly Supervised Segmentation by Pixel-to-Segment Contrastive Learning

ICLR 2021poster

Weakly supervised segmentation requires assigning a label to every pixel based on training instances with partial annotations such as image-level tags, object bounding boxes, labeled points and scribbles. This task is challenging, as coarse annotations (tags, boxes) lack precise pixel localization w…
