On the Value of Oversampling for Deep Learning in Software Defect Prediction
IEEE TRANSACTIONS ON SOFTWARE ENGINEERING, 48(8), 3103–3116.
Contributors: R. Yedida n & T. Menzies n
author keywords: Deep learning; Tuning; Predictive models; Standards; Prediction algorithms; Training; Tools; Defect prediction; oversampling; class imbalance; neural networks

Simpler Hyperparameter Optimization for Software Analytics: Why, How, When?
IEEE TRANSACTIONS ON SOFTWARE ENGINEERING, 48(8), 2939–2954.
Contributors: A. Agrawal*, X. Yang n, R. Agrawal n, R. Yedida n , X. Shen n & T. Menzies n
author keywords: Software analytics; hyperparameter optimization; defect prediction; bad smell detection; issue close time; bug reports
TL;DR:
The simple DODGE works best for data sets with low “intrinsic dimensionality” and very poorly for higher-dimensional data; nearly all the SE data seen here was intrinsically low-dimensional, indicating that DODGE is applicable for many SE analytics tasks.
