Feature selection in software defect prediction: A comparative study
Misha Kakkar, Sarika Jain · 2016
Software has become a vital part of human's life - hence building defect free software is a must. Various studies have been carried out to predict defects, probability of defect prone modules, and implementation of defect prediction for real life softwares. The focus of this paper is towards building a framework using attribute selection for defect prediction based on five classifiers IBk, KStar, LWL, Random Tree and Random Forest. Performance comparison is done on the basis of accuracy and ROC values. The result and analysis shows that the framework has reduced total number of attributes used for each dataset by 6 folds on average, also LWL performed better than other four classifiers when tested with 10 Cross Validation (10CV) and percentage split of 66%.
