Block sparse representation for pattern classification: Theory, extensions and applications.
Pattern Recognition(2019)
摘要
•We give theoretical guarantees for the block sparse representation based classifier.•A RBSRC (robust block sparse representation based classifier) framework is given.•We devise an efficient half-quadratic optimization algorithm for RBSRC.•Using RBSRC as a general platform, we propose three robust classifiers.
