Abstract
Cilj ovog diplomskog rada je istražiti problem predviđanja pogrešaka u programskoj podršci koristeći različite metode strojnog učenja. Glavni izazov bio je neuravnoteženost klasa unutar korištenih skupova podataka, što je negativno utjecalo na učinkovitost klasifikacijskih modela. U cilju poboljšanja performansi modela, primijenjene su tehnike odabira značajki (Pearsonov koeficijent korelacije, zajednička informacija, ANOVA F-test i slijedna pretraga unaprijed) te metode uzorkovanja (nasumično preuzorkovanje, nasumično poduzorkovanje i SMOTE). Najbolje rezultate postigla je kombinacija NB s tehnikom odabira značajki pomoću omotača slijedne pretrage unaprijed, kao i DT u kombinaciji s nasumičnim preuzorkovanjem. Unatoč tome, pokazalo se da ne postoji univerzalna metoda koja donosi optimalne rezultate za sve skupove podataka, već je potrebno prilagoditi pristup ovisno o specifičnostima problema.
Abstract (english)
The aim of this thesis is to explore the problem of software defect prediction using various machine learning methods. The main challenge was the class imbalance within the datasets used, which negatively impacted the performance of classification models To improve model performance, feature selection techniques (Pearson correlation coefficient, mutual information, ANOVA F-test, and sequential forward selection) and sampling methods (random oversampling, random undersampling, and SMOTE) were applied. The best results were achieved by combining Naive Bayes with the sequential forward selection wrapper feature selection method, as well as decision trees combined with random oversampling. However, it was found that no universal method guarantees optimal results for all datasets, and the approach must be adapted based on the specific characteristics of the problem.
