Deep J-Sense: Accelerated MRI Reconstruction via Unrolled Alternating Optimization
Marius Arvinte, Sriram Vishwanath, Ahmed H. Tewfik +1
Accelerated multi-coil magnetic resonance imaging reconstruction has seen a substantial recent improvement combining compressed sensing with deep learning. However, most of these m…
Robust Face Verification via Disentangled Representations
Marius Arvinte, Ahmed H. Tewfik, Sriram Vishwanath
We introduce a robust algorithm for face verification, i.e., deciding whether twoimages are of the same person or not. Our approach is a novel take on the idea ofusing deep generat…
Detecting Patch Adversarial Attacks with Image Residuals
Marius Arvinte, Ahmed Tewfik, Sriram Vishwanath
We introduce an adversarial sample detection algorithm based on image residuals, specifically designed to guard against patch-based attacks. The image residual is obtained as the d…
A Relax-and-Round Approach to Complex Lattice Basis Reduction
Marius Arvinte, Ahmed H. Tewfik
We propose a relax-and-round approach combined with a greedy search strategy for performing complex lattice basis reduction. Taking an optimization perspective, we introduce a rela…
