New Theory Explains CNNs for Imaging Inverse Problems

Researchers have developed a new theoretical framework, the Local-Equivariant MMSE (LE-MMSE) estimator, to better understand how supervised convolutional neural networks (CNNs) solve imaging inverse problems. This theory incorporates key CNN inductive biases like translation equivariance and locality, providing an analytic formula that closely matches the performance of trained networks across various tasks and datasets. The findings offer insights into the differences between physics-aware and physics-agnostic estimators and the impact of training data characteristics. AI
