Improving Relevancy Filter Methods for Cross-Project Defect Prediction

2015

Context: Cross-project defect prediction (CPDP)research has been popular. One of the techniques for CPDP isa relevancy filter which utilizes clustering algorithms to selecta useful subset of the cross-project data. Their performanceheavily relies on the quality …

On Applicability of Fixed-Size Moving Windows for ANN-Based Effort Estimation

2016

BACKGROUND: Several studies in software effort estimation have found that it can be effective to use a window of recent projects as training data for building an effort estimation model. The generality of the windowing …

An Application of the PageRank Algorithm to Commit Evaluation on Git Repository

2017

Many empirical studies have reported notable theories or methods for evaluating or predicting code quality through analyses of code repositories. This paper has yet another point of view: it focuses on "commits" rather than source …

A replication study on the effects of weighted moving windows for software effort estimation

2016 · ACM International Conference Proceeding Series

Context: Recent studies have shown that estimation accuracy can be affected by only using a window of recent projects as training data for building an effort estimation model. The idea has been extended for regression-based …

Large-Scale Evaluation of Method-Level Bug Localization with FinerBench4BL

2023 · arXiv (Cornell University)

Bug localization is an important aspect of software maintenance because it can locate modules that need to be changed to fix a specific bug. Although method-level bug localization is helpful for developers, there are only …
