As the paper said “For the CS-MRI application, a single policy network is trained to handle multiple sampling ratios (with x2/x4/x8 acceleration) and noise levels (5/10/15), simultaneously. Similarly, one policy network is learned for phase retrieval under different settings. “, does the motioned training datasets of applications (MRI, PR, CT, SPI) are all PASCAL VOC dataset? Because there is a domain shift between the training datasets and the testing dataset in (MRI, CT, SPI).
