Iterative shrinkage-thresholding algorithm with inertia and dry friction for convolutional dictionary learning

The iterative shrinkage-thresholding algorithm (ISTA) is often used to address the convolutional dictionary learning problem. However, the ISTA algorithm is easy to fall into the local minimum, and some atoms in the convolution dictionary change little when updated. Therefore, in this paper, we prop...
