Bogus Bugs, Duplicates, and Revealing Comments: Data Quality Issues in NPR

Julian Aron Prenner, Romain Robbes

The performance of a machine learning system is not only determined by the model but also, to a substantial degree, by the data it is trained on. With the increasing use of machine…

Simple Fault Localization using Execution Traces

Julian Aron Prenner, Romain Robbes

Traditional spectrum-based fault localization (SBFL) exploits differences in a program's coverage spectrum when run on passing and failing test cases. However, such runs can provid…
