New Frontiers for Learning with Limited Labels or Data
ECCV 2020 Tutorial, Glasgow, Scotland, UK
Learning from limited data or supervision has garnered much research interest and many ideas to solve it are now well-established. Among them, learning from 1) partial or imperfect labels and 2) data from other related domains (synthetic data), modalities (text/audio/3D) or tasks have been extensively addressed in past tutorials/workshops. To improve network generalization when learning with limited data, the ideas of zero-, few-shot, meta- and task-transfer learning are ubiquitous. So, what's next? Are there new sub-problems that we have not yet investigated? Are there recent breakthroughs in other areas of vision and learning that can help us to better tackle this problem? Can we enable new applications?
To foster discussion and inspire new ideas along these lines, in this tutorial we will focus on new frontiers of learning with limited labels or data. We will explore emerging sub-problems, such as 1) omni-supervision, which is creating unified frameworks for learning from the entire spectrum of supervision -- with completely unsupervised, semi/weakly-supervised, to full-supervised data and 2) deep dreaming, which involves effectively inverting networks to generate training data. We will present some recent breakthroughs in other vision problems including, but not limited to, neural rendering; biologically-inspired self-learning and self-supervised image representation learning by exploiting video correspondences and 3D mesh reconstruction that can help to solve this problem. Finally, we will present some new applications including self-supervisedly learned discovery of visual object attributes.
