Call for Papers

Deep learning has shown impressive performance improvements on a variety of tasks in vision, speech and language domains. However, a large amount of labeled data is often needed to deliver these remarkable accuracy gains. The goal of this workshop is to facilitate discussion on the role of equivariance/ invariance of feature maps, including their synergies with unsupervised/self-supervised learning methods that define and solve auxiliary tasks on unlabeled data to learn representations (such as auto-encoding, context prediction, predicting one modality from other, etc.), towards reducing the dependence on labeled examples. Apart from the group-theoretical notions of equivariance and invariance, the workshop also welcomes contributions with a non-group-theoretical and relaxed notion of equivariance and invariance with respect to a set of transformations (possibly input specific and learned from data).

We welcome submissions in topics including (but not limited to):

  • Learning desired equivariances / invariances for a given prediction task from data (e.g., from massive amounts of unlabeled data, from auxiliary labels, from multiple views, or from side-information when available)
  • Learning transferable invariances: feature maps that are equivariant/invariant with respect to domain- or task-specific nuisance factors while being suitable for transfer learning (on a target domain or task)
  • Learning equivariant / invariant feature maps from structure when it is available (e.g., temporal ordering structure in videos)
  • Incorporating known equivariances / invariances (from domain knowledge, e.g., rotation and scale for images, permutations for sets, etc.) as inductive biases
  • Architectural priors for equivariant features 
  • Synergies with unsupervised / self-supervised feature learning methods that define and solve auxiliary tasks on unlabeled data (such as auto-encoding, context prediction, etc.) to learn representation maps
  • Hierarchical representations with interplay between invariance and equivariance 
  • Visualizing/understanding the equivariances and invariances learned by current popular deep neural net architectures

Submission instructions.  
Submissions should be a maximum of 4 pages (excluding references) and should not have been published/presented at other venues. However, work currently under review but not accepted anywhere is welcome. The workshop will not have archival proceedings. All accepted papers will be presented at the poster sessions. Selected top submissions will also be given spotlight presentation slots.
