Title Software Defect Prediction Using Bayesian Networks and Kernel Methods

Description In this thesis, we use source code metrics together with some process and developer
metrics to predict defect proneness. By learning from the data sets, we model the interactions among the metrics and determine the most important metrics using Bayesian
networks. As a result of our modeling, we not only reveal the influential relationships
among the metrics, but also the set of most important metrics that are relatively more
effective on defectiveness. Furthermore, it is possible to make probabilistic reasoning
about the dependencies between the metrics and defect proneness.

Description Furthermore, we focus on the similarities of code patterns among different classes (or
files) of a software system, to predict the defect proneness and the number of defects.
We wonder if the extent of similarity between two source codes is related with the
extent of similarity in their defectiveness where the similarity is measured in terms of
both syntactic and semantic features. At the end of our experiments, we show that
support vector machines (SVM) with a precalculated kernel matrix performs better
than the SVM with the usual linear and RBF kernels and generates comparable results
with the famous defect prediction methods like linear logistic regression and J48 in
terms of the area under the curve (AUC).
