Representation Learning via Cauchy Convolutional Sparse Coding

Perla Mayo, Oktay Karakuş, Robin Holmes +1

In representation learning, Convolutional Sparse Coding (CSC) enables unsupervised learning of features by jointly optimising both an \(\ell_2\)-norm fidelity term and a sparsity e…

Convergence Guarantees for Non-Convex Optimisation with Cauchy-Based Penalties

Oktay Karakus, Perla Mayo, Alin Achim

In this paper, we propose a proximal splitting methodology with a non-convex penalty function based on the heavy-tailed Cauchy distribution. We first suggest a closed-form expressi…
