Fast Equivariant Imaging: Accelerating Unsupervised Learning and Model Adaptation via Inexact Splitting
arXiv:2507.06764v5 Announce Type: replace-cross Abstract: In this work, we propose Fast Equivariant Imaging (FEI), a novel unsupervised learning framework to rapidly and efficiently train deep imaging networks without ground-truth data. FEI reformulates the EI objective through an inexact variable-splitting scheme, decoupling network training from an auxiliary restoration step implemented with a plug-and-play denoiser, this novel unsupervised scheme shows superior efficiency and performance compared to the standard Equivariant Imaging paradigm. In particular, our FEI schemes achieve an order-o
The continuous drive for more efficient and robust unsupervised learning methods in AI, particularly for computer vision tasks, underpins the development of FEI at this juncture.
This development allows for faster and more efficient training of deep imaging networks without reliance on scarce labeled ground-truth data, accelerating AI deployment in data-poor environments.
The prior bottleneck of ground-truth data for training deep imaging networks is significantly alleviated, enabling broader application and faster iteration cycles for AI in fields like medical imaging or surveillance.
