This problem is formally known as the sparsity of the ratings' matrix, because this is the structure that holds user preferences. This paper outlines a Collaborative Filtering Recommender System that tries to amend this situation. After applying Singular Value Decomposition to reduce the dimensionality of the data, our system makes use of a dynamic Artificial Neural Network architecture with boosted learning to predict user ratings. Furthermore we use the concept of k-separability to deal with the resulting noisy data, a methodology not yet tested in Recommender Systems. The combination of these techniques applied to the MovieLens datasets seems to yield promising results.<\/jats:p>","DOI":"10.1142\/s0218213012500017","type":"journal-article","created":{"date-parts":[[2012,1,6]],"date-time":"2012-01-06T00:57:11Z","timestamp":1325811431000},"page":"1250001","source":"Crossref","is-referenced-by-count":0,"title":["APPLYING k-SEPARABILITY TO COLLABORATIVE RECOMMENDER SYSTEMS"],"prefix":"10.1142","volume":"21","author":[{"given":"GEORGIOS","family":"ALEXANDRIDIS","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, National Technical University of Athens, Zografou, 157 80, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"GEORGIOS","family":"SIOLAS","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, National Technical University of Athens, Zografou, 157 80, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ANDREAS","family":"STAFYLOPATIS","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, National Technical University of Athens, Zografou, 157 80, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2012,4,5]]},"reference":[{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1109\/TKDE.2005.99"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1016\/0306-4573(88)90021-0"},{"key":"rf15","doi-asserted-by":"publisher","DOI":"10.1017\/S0269888906000397"},{"key":"rf17","doi-asserted-by":"publisher","DOI":"10.1109\/TSMCC.2010.2040275"},{"key":"rf18","doi-asserted-by":"publisher","DOI":"10.1109\/TSMCA.2003.818877"},{"key":"rf20","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-24571-1_39"},{"key":"rf21","doi-asserted-by":"publisher","DOI":"10.1142\/S0218213007003540"},{"key":"rf22","first-page":"1","volume":"38","author":"Symeonidis P.","journal-title":"IEEE Transactions on Systems, Man and Cybernetics, Part A: Systems and Humans"},{"key":"rf24","doi-asserted-by":"publisher","DOI":"10.1109\/TSMCA.2007.897696"},{"key":"rf25","doi-asserted-by":"crossref","first-page":"203","DOI":"10.3233\/AIC-2008-0437","volume":"21","author":"Cantador I.","journal-title":"AI Communications"},{"key":"rf27","doi-asserted-by":"publisher","DOI":"10.1145\/963770.963772"},{"key":"rf30","first-page":"313","volume":"2","author":"Zhang T.","journal-title":"Journal of Machine Learning Research"},{"key":"rf31","unstructured":"M.
