Researchers have introduced Fast Equivariant Imaging (FEI), a new unsupervised learning framework designed to accelerate the training of deep imaging networks. FEI reformulates the Equivariant Imaging objective using an inexact variable-splitting scheme, separating network training from an auxiliary restoration step. This novel approach demonstrates a tenfold acceleration in training time for tasks like X-ray CT reconstruction and image inpainting compared to standard Equivariant Imaging, while also improving generalization performance and enabling efficient test-time adaptation.
