On the relationship between refactoring actions and bugs: a differentiated replication

2020

Software refactoring aims at improving code quality while preserving the system's external behavior. Although in principle refactoring is a behavior-preserving activity, a study presented by Bavota etal in 2012 reported the proneness of some refactoring …

Evaluating SZZ Implementations Through a Developer-informed Oracle

2021 · arXiv (Cornell University)

The SZZ algorithm for identifying bug-inducing changes has been widely used to evaluate defect prediction techniques and to empirically investigate when, how, and by whom bugs are introduced. Over the years, researchers have proposed several …

Automating Code-Related Tasks Through Transformers: The Impact of Pre-training

2023 · arXiv (Cornell University)

Transformers have gained popularity in the software engineering (SE) literature. These deep learning models are usually pre-trained through a self-supervised objective, meant to provide the model with basic knowledge about a language of interest (e.g., …

Source Code Recommender Systems: The Practitioners' Perspective

2023

The automatic generation of source code is one of the long-lasting dreams in software engineering research. Several techniques have been proposed to speed up the writing of new code. For example, code completion techniques can …
