2020
Scientific Programming
Preserved Fulltext
Finally, two algorithms were proposed to train software defect prediction models based on the weighted extreme learning machine. ...
To identify software modules that are more likely to be defective, machine learning has been used to construct software defect prediction (SDP) models. ...
