EquiCaps: Predictor-Free Pose-Aware Pre-Trained Capsule Networks

ICCV 2025poster

Learning self-supervised representations that are invariant and equivariant to transformations is crucial for advancing beyond traditional visual classification tasks. However, many methods rely on predictor architectures to encode equivariance, despite evidence that architectural choices, such as c…

Introducing Routing Uncertainty in Capsule Networks

NeurIPS 2020poster

Rather than performing inefficient local iterative routing between adjacent capsule layers, we propose an alternative global view based on representing the inherent uncertainty in part-object assignment. In our formulation, the local routing iterations are replaced with variational inference of part…
