Abstract

U ovom je radu obrađen problem odabira značajki skupa podataka korištenjem evolucijskih algoritama kao metode pretraživanja prostora stanja. Predstavljena je teorijska osnova odabira značajki i evolucijskih algoritama te je programski izveden algoritam koji kombinira metode filtera i metodu omotača, koristeći simetričnu nesigurnost, Relief i Fischer metriku te stroj potpornih vektora i klasifikator Naivan Bayes. Kvaliteta algoritma ispitana je na dva skupa podataka s različitim karakteristikama, Wisconsin Diagnostic Breast Cancer i MADELON.

Abstract (english)

In this paper feature selection using evolutionary algorithms was discussed. The theoretical basis of feature selection and evolutionary algorithms was given, as well as a potential solution combining filter and wrapper methods, including the Relief, Fischer and symmetrical uncertainty measures as well as Naive Bayes and SVM models. The algorithm’s quality was assessed on two datasets with differing characteristics, Wisconsin Diagnostic Breast Cancer and MADELON.
