Forward propagation of the sparse coding layer is carried out by solving the optimization problem in(4). In this paper, we adopt the fast iterative shrinkage thresholding algorithm(FISTA)[1]. The results are provided in Figure B.1. In Figure C.1, we provide a visualization of the learned dictionary in the first layer of SDNet-18 trainedonImageNet.
