PPT-The Horseshoe Estimator for Sparse Signals

Reading Group Presenter Zhen Hu Cognitive Radio Institute Friday October 08 2010 Authors Carlos M Carvalho Nicholas G Polson and James G Scott Outline Introduction Robust Shrinkage of Sparse Signals. Such matrices has several attractive properties they support algorithms with low computational complexity and make it easy to perform in cremental updates to signals We discuss applications to several areas including compressive sensing data stream Volkan .
