Abstract
U ovom diplomskom radu istražena je učinkovitost algoritama strojnog učenja - logističke regresije, slučajne šume i SVM-a - u detekciji prijevara s kreditnim karticama na nebalansiranim podacima. Primijenjene su tehnike undersampling, oversampling, SMOTE i ADASYN kako bi se izbalansirali podaci. Rezultati su analizirani na nebalansiranom i balansiranom skupu podataka. Rezultati pokazuju kako se balansiranje podataka značajno može poboljšati pomoću tih tehnika, te kako takvi balansirani skupovi dovode do poboljšanja performansi algoritama u detekciji prijevara.
Abstract (english)
This thesis examines the effectiveness of machine learning algorithms - logistic regression, random forest, and SVM - in credit card fraud detection on imbalanced data. Undersampling, oversampling, SMOTE, and ADASYN techniques were applied to balance the data. Results were evaluated on both imbalanced and balanced datasets. The findings indicate that data balancing techniques, particularly oversampling and SMOTE, significantly enhance performance by addressing class imbalance issues, leading to improved fraud detection accuracy.
