Joint Learning of Cartesian under Sampling Andre Construction for Accelerated MRI

ICASSP 2020accepted

Magnetic Resonance Imaging (MRI) is considered today the golden-standard modality for soft tissues. The long acquisition times, however, make it more prone to motion artifacts as well as contribute to the relative high costs of this examination. Over the years, multiple studies concentrated on desig…

SEBOOST - Boosting Stochastic Learning Using Subspace Optimization Techniques

NeurIPS 2016poster

We present SEBOOST, a technique for boosting the performance of existing stochastic optimization methods. SEBOOST applies a secondary optimization process in the subspace spanned by the last steps and descent directions. The method was inspired by the SESOP optimization method for large-scale proble…
