A Two-Stage Subspace Trust Region Approach for Deep Neural Network Training
Viacheslav Dudar, Giovanni Chierchia, Emilie Chouzenoux +2
In this paper, we develop a novel second-order method for training feed-forward neural nets. At each iteration, we construct a quadratic approximation to the cost function in a low…
SAR image despeckling through convolutional neural networks
G. Chierchia, D. Cozzolino, G. Poggi +1
In this paper we investigate the use of discriminative model learning through Convolutional Neural Networks (CNNs) for SAR image despeckling. The network uses a residual learning s…
A Non-Local Structure Tensor Based Approach for Multicomponent Image Recovery Problems
Giovanni Chierchia, Nelly Pustelnik, Beatrice Pesquet-Popescu +1
Non-Local Total Variation (NLTV) has emerged as a useful tool in variational methods for image recovery problems. In this paper, we extend the NLTV-based regularization to multicom…
