This book focuses on software defect prediction (SDP) in order to avoid threats related to quality, reliability and safety. It details advanced machine/deep learning technologies to discuss strategies for identifying and preventing such issues, and introduces innovative approaches to address feature irrelevance and redundancy, data imbalance in defect data, selection of representative module subsets for cross-version defect prediction, and managing data distribution variances in cross-project defect prediction.


The book is organized into eight chapters, systematically covering various aspects of software defect prediction.  First, chapter 1 “Introduction“ explains the socio-economic significance and importance of software defect prediction. Next, chapter 2 “Literature Review“ reviews and analyzes current technologies and their applications in defect prediction. Then chapter 3 “Feature Learning“ discusses how to extract effective features from software engineering data using machine learning techniques. While chapter 4 “Handling Class Imbalance“ introduces strategies to address the class imbalance in software defect data, chapter 5 “Cross-Version Defect Prediction“ analyzes the application of historical version data to enhance the accuracy of prediction models. Subsequently, chapter 6 “Cross-Project Defect Prediction“ discusses how to mitigate data discrepancies between projects through transfer learning, and chapter 7 “Effort-Aware Defect Prediction“ delves into new technologies to rank software modules based on the defect density. Eventually, chapter 8 “Conclusion and Future Trends“ summarizes the book and outlines future research directions.


The book mainly targets academic researchers and graduate students, particularly those focusing on the intersection of software engineering and machine learning. It is also intended for software engineers and data scientists working on enhancing the quality and safety of software.
