Abstract English We investigate the application of non-convex penalized least<br> squares for parameter estimation in the Volterra model. Sparsity<br> is promoted by introducing a weighted !q penalty on the<br> parameters and efficient batch and time recursive algorithms<br> are devised based on the cyclic coordinate descent approach.<br> Numerical examples illustrate the improved performance of<br> the proposed algorithms as compared the weighted !1 norm.
