For instance, an attribute's value, or a class label, in a given example was known to be a or b but definitely not c or d. Previous research in machine learning usually either \u201cdisambiguated\u201d the value (by giving preference to a or b), or replaced it with a \u201cdon't-know\u201d symbol. Neither approach is satisfactory: while the former distorts the available information by pretending precise knowledge, the latter ignores the fact that at least something is known. Our experiments confirm the intuition that classification performance is indeed impaired if the ambiguities are not handled properly. In the research reported here, we limited ourselves to the realm of the relatively simple nearest-neighbor classifiers and investigated a few alternative solutions. The paper describes the techniques we used and describes their behavior in experimental domains.<\/jats:p>","DOI":"10.1142\/s0218213008003996","type":"journal-article","created":{"date-parts":[[2008,6,24]],"date-time":"2008-06-24T09:38:40Z","timestamp":1214300320000},"page":"449-463","source":"Crossref","is-referenced-by-count":0,"title":["HANDLING AMBIGUOUS VALUES IN INSTANCE-BASED CLASSIFIERS"],"prefix":"10.1142","volume":"17","author":[{"given":"HANS","family":"HOLLAND","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Miami, USA"}]},{"given":"MIROSLAV","family":"KUBAT","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Miami, USA"}]},{"given":"JAN","family":"\u017dI\u017dKA","sequence":"additional","affiliation":[{"name":"College of Science, Masaryk University, Kamenice 126\/3, 625 00 Brno, Czech Republic"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4757-0450-1"},{"key":"rf2","volume-title":"Nearest-Neighbor Classification Techniques","author":"Dasarathy B.
