Associate Professor, Department of Software Engineering, Jeonbuk National University, South Korea
Research focuses on the intersection of Artificial Intelligence and Software Engineering
Primary interests include AI4SE (applying AI to improve software quality) and SE4AI (applying SE techniques to enhance AI-based systems)
Specific research topics: mining software repositories, software defect prediction, bug report prediction, software reliability engineering, Web/Edge service QoS prediction, and fault localization
In defect prediction, developed hyperparameter optimization methods, cross-project models for cold-start problems, heterogeneous models for mismatched feature dimensions, and novel cost-sensitive and boosting techniques for class imbalance
Employs diverse ML/DL techniques including multi-output CNNs, GANs, Bayesian optimization, Explainable AI, AutoML, TabNet, self-supervised learning, deep domain adaptation, deep metric learning, and image translation
Proposed a matrix factorization–based collaborative filtering method for Web service QoS prediction in cloud environments
