Researchers have developed a new method to integrate known data symmetries into neural network architectures, specifically focusing on SE(2) invariance which accounts for both translations and rotations. This approach uses provably optimal invariant feature maps that are minimal and information-preserving, allowing seamless integration into existing models without altering nonlinearities or normalization layers. Experiments demonstrate that this plug-and-play module for convolutional neural networks achieves competitive accuracy with lower computational costs compared to current state-of-the-art equivariant methods, while also offering insights into the interplay between equivariance and invariance for model robustness and flexibility.
