(English Abstract)
Software defect prediction (SDP) can help optimally allocate software testing resources on fault-prone modules. Typically, local data within a company are used to build classifiers. Unlike such Within-Project Defect Prediction (WPDP), there may exist some cases, e.g., pilot projects, without any collected data from historical projects. Cross-project defect prediction (CPDP) using data from other projects can be employed in such cases. The defect prediction performance may be degraded in the presence of irrelevant or redundant information. To address this issue, various feature selection techniques have been suggested. Until now, there has been no research on identifying effective feature selection techniques for CPDP. We present a comparative framework using feature selection to produce a high performance for CPDP. We compare eight existing feature selection techniques, for three CPDP and one WPDP model, based on feature subset evaluators and feature ranking methods. After the features are chosen that perform the best, classifiers are built, tested, and evaluated using the statistical significance and effect size tests. Hybrid Instance Selection using Nearest-Neighbor (HISNN) is better than the other CPDP models and comparable to the WPDP model. Results from the comparison show that a different distribution, class imbalance and feature selection should be considered to obtain a high performance CPDP model.
