Quantum Algorithms for Non-smooth Non-convex Optimization

Neural Information Processing Systems

This paper considers the problem of finding the (ฮด,วซ)-Goldstein stationary point of the Lipschitz continuous objective, which is a rich funct ion class to cover a large number of important applications. We construct a nove l zeroth-order quantum estimator for the gradient of the smoothed surrogate.


Reducing Information Bottleneck for Weakly Supervised Semantic Segmentation

Neural Information Processing Systems

Our experimental evaluations demonstrate that this simple modification significantly improves the quality of localization maps on both the P ASCAL VOC 2012 and MS COCO 2014 datasets, exhibiting a new state-of-the-art performance for weakly supervised semantic segmentation.








Cascaded Dilated Dense Network with Two-step Data Consistency for MRI Reconstruction

Neural Information Processing Systems

Compressed Sensing MRI (CS-MRI) aims at reconstrcuting de-aliased images fromsub-Nyquist samplingk-space datatoaccelerate MRImaging. Inspired by recent deep learning methods, we propose a Cascaded Dilated Dense Network (CDDN)forMRIreconstruction.
