For\n\t\t\t every method and every data set 30 experiments of ten-fold cross validation\n\t\t\t were conducted and then means and sample standard deviations were computed. Our\n\t\t\t results show that for a specific data set it is essential to choose an\n\t\t\t appropriate discretization method since performance of discretization methods\n\t\t\t differ significantly. However, in general, among all of these discretization\n\t\t\t methods there is no statistically significant worst or best method. Thus, in\n\t\t\t practice, for a given data set the best discretization method should be\n\t\t\t selected individually.<\/jats:p>","DOI":"10.3233\/fi-2009-121","type":"journal-article","created":{"date-parts":[[2019,12,2]],"date-time":"2019-12-02T22:49:55Z","timestamp":1575326995000},"page":"121-131","source":"Crossref","is-referenced-by-count":2,"title":["An Extended Comparison of Six Approaches to\t\t\t Discretization \u2013 A Rough Set Approach"],"prefix":"10.1177","volume":"94","author":[{"given":"Piotr","family":"Blajdo","sequence":"first","affiliation":[{"name":"Department of Expert Systems and Artificial\r\t\t\t Intelligence University of Information Technology and Management 35-225\r\t\t\t Rzeszow, Poland.
