Equivariance by Contrast: Identifiable Equivariant Embeddings from Unlabeled Finite Group Actions

Tobias Schmidt, Steffen Schneider, Matthias Bethge

We propose Equivariance by Contrast (EbC) to learn equivariant embeddings from observation pairs $(\mathbf{y},g\cdot \mathbf{y})$, where $g$ is drawn from a finite group acting o…
