Query: A Trained Regularization Approach Based on Born Iterative Method for
  Electromagnetic Imaging   A trained-based Born iterative method (TBIM) is developed for electromagnetic
imaging (EMI) applications. The proposed TBIM consists of a nested loop; the
outer loop executes TBIM iteration steps, while the inner loop executes a
trained iterative shrinkage thresholding algorithm (TISTA). The applied TISTA
runs linear Landweber iterations implemented with a trained regularization
network designed based on U-net architecture. A normalization process was
imposed in TISTA that made TISTA training applicable within the proposed TBIM.
The iterative utilization of the regularization network in TISTA is a
bottleneck that demands high memory allocation through the training process.
Therefore TISTA within each TBIM step was trained separately. The TISTA
regularization network in each TBIM step was initialized using the weights from
the previous TBIM step. The above approach achieved high-quality image
restoration after running few TBIM steps while maintained low memory allocation
through the training process. The proposed framework can be extended to Newton
or quasi-Newton schemes, where within each Newton iteration, a linear ill-posed
problem is optimized that differs from one example to another. The numerical
results illustrated in this work show the superiority of the proposed TBIM
compared to the conventional sparse-based Born iterative method (SBIM).
