Query: A systematic mapping study on cross-project defect prediction   Cross-Project-Defect Prediction as a sub-topic of defect prediction in
general has become a popular topic in research. In this article, we present a
systematic mapping study with the focus on CPDP, for which we found 50
publications. We summarize the approaches presented by each publication and
discuss the case study setups and results. We discovered a great amount of
heterogeneity in the way case studies are conducted, because of differences in
the data sets, classifiers, performance metrics, and baseline comparisons used.
Due to this, we could not compare the results of our review on a qualitative
basis, i.e., determine which approaches perform best for CPDP.
