Another interesting related problem based on linear equality constraints, namely the sparse null space (SNS) problem, first appeared in 1986 and has since inspired results on sparse basis pursuit. In this paper, we investigate the relation between the SNS problem and the analysis dictionary learning (ADL) problem, and show that the SNS problem plays a central role, and may be utilized to solve dictionary learning problems. Moreover, we propose an efficient algorithm of sparse null space basis pursuit (SNS-BP) and extend it to a solution of ADL. Experimental results on numerical synthetic data and real-world data are further presented to validate the performance of our method."}],"issue":"3","doi":"10.1137/15m1030376","extern":"1","date_created":"2024-10-15T11:20:55Z","type":"journal_article","month":"08","date_updated":"2024-12-19T13:05:21Z","scopus_import":"1","author":[{"full_name":"Bian, Xiao","first_name":"Xiao","last_name":"Bian"},{"last_name":"Krim","first_name":"Hamid","full_name":"Krim, Hamid"},{"orcid":"0000-0001-9699-8730","first_name":"Alexander","full_name":"Bronstein, Alexander","id":"58f3726e-7cba-11ef-ad8b-e6e8cb3904e6","last_name":"Bronstein"},{"first_name":"Liyi","full_name":"Dai, Liyi","last_name":"Dai"}],"page":"1107-1126","publication_identifier":{"eissn":["1936-4954"]},"year":"2016","volume":9}
