Core Concepts
Novel nonsmooth regularization improves deep neural network performance for matrix completion.
Abstract
The article discusses using deep fully connected neural networks (FCNNs) for matrix completion and the challenges of overfitting due to high capacity. By introducing nonsmooth regularization terms, the authors propose a new algorithm, DNN-NSR, to control overfitting and improve generalizability. The gradual addition of these regularization terms enhances the performance of deep neural networks in matrix completion tasks. The proposed method outperforms existing linear and nonlinear algorithms in simulations.
