The original na\u00efve Bayes scheme, does, however, have a serious weakness, namely, the harmful effect of redundant predictors. In this paper, we study how to apply a regularization technique to learn a computationally efficient classifier that is inspired by na\u00efve Bayes. The proposed formulation, combined with an L<jats:sub>1<\/jats:sub>-penalty, is capable of discarding harmful, redundant predictors. A modification of the LARS algorithm is devised to solve this problem. We tackle both real-valued and discrete predictors, assuring that our method is applicable to a wide range of data. In the experimental section, we empirically study the effect of redundant and irrelevant predictors. We also test the method on a high dimensional data set from the neuroscience field, where there are many more predictors than data cases. Finally, we run the method on a real data set than combines categorical with numeric predictors. Our approach is compared with several na\u00efve Bayes variants and other classification algorithms (SVM and kNN), and is shown to be competitive.<\/jats:p>","DOI":"10.1142\/s021821301350019x","type":"journal-article","created":{"date-parts":[[2013,8,23]],"date-time":"2013-08-23T04:52:26Z","timestamp":1377233546000},"page":"1350019","source":"Crossref","is-referenced-by-count":1,"title":["AN L<sub>1<\/sub>-REGULARIZED NA\u00cfVE BAYES-INSPIRED CLASSIFIER FOR DISCARDING REDUNDANT AND IRRELEVANT PREDICTORS"],"prefix":"10.1142","volume":"22","author":[{"given":"DIEGO","family":"VIDAURRE","sequence":"first","affiliation":[{"name":"Computational Intelligence Group, Universidad Polit\u00e9cnica de Madrid, Spain"}]},{"given":"CONCHA","family":"BIELZA","sequence":"additional","affiliation":[{"name":"Computational Intelligence Group, Universidad Polit\u00e9cnica de Madrid, Spain"}]},{"given":"PEDRO","family":"LARRA\u00d1AGA","sequence":"additional","affiliation":[{"name":"Computational Intelligence Group, Universidad Polit\u00e9cnica de Madrid, Spain"}]}],"member":"219","published-online":{"date-parts":[[2013,8,22]]},"reference":[{"key":"p_2","doi-asserted-by":"publisher","DOI":"10.1023\/A:1007413511361"},{"key":"p_3","doi-asserted-by":"publisher","DOI":"10.1111\/j.1751-5823.2001.tb00465.x"},{"key":"p_6","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2105-10-410"},{"key":"p_7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbi.2005.05.004"},{"key":"p_8","first-page":"239","author":"Pazzani M.
