Ankur Tagra, Haoxiang Zhang, Gopi Krishnan Rajbahadur +1
Reopened bugs can degrade the overall quality of a software system since they require unnecessary rework by developers. Moreover, reopened bugs also lead to a loss of trust in the…
The Impact of Using Regression Models to Build Defect Classifiers
Gopi Krishnan Rajbahadur, Shaowei Wang, Yasutaka Kamei +1
It is common practice to discretize continuous defect counts into defective and non-defective classes and use them as a target variable when building defect classifiers (discretize…
Impact of Discretization Noise of the Dependent variable on Machine Learning Classifiers in Software Engineering
Gopi Krishnan Rajbahadur, Shaowei Wang, Yasutaka Kamei +1
Researchers usually discretize a continuous dependent variable into two target classes by introducing an artificial discretization threshold (e.g., median). However, such discretiz…
Revisiting the Impact of Dependency Network Metrics on Software Defect Prediction
Lina Gong, Gopi Krishnan Rajbahadur, Ahmed E. Hassan +1
Software dependency network metrics extracted from the dependency graph of the software modules by the application of Social Network Analysis (SNA metrics) have been shown to impro…
An Empirical Study of the Characteristics of Popular Minecraft Mods
Daniel Lee, Gopi Krishnan Rajbahadur, Dayi Lin +3
It is becoming increasingly difficult for game developers to manage the cost of developing a game, while meeting the high expectations of gamers. One way to balance the increasing…
