Instance Hardness-Based Relevance for Imbalanced Regression
Vitor M. Leitao, Juscimara G. Avelino, George D. C. Cavalcanti +1
Imbalanced regression problems arise when the target variable has an asymmetric distribution, resulting in underrepresented value ranges in the dataset. Traditional approaches for…
Multi-stage Dynamic Selection for Cross-Project Defect Prediction
Juscimara G. Avelino, Juscelino S. A. Junior, George D. C. Cavalcanti +1
Cross-Project Defect Prediction (CPDP) involves building models using data from external projects, called training projects, to predict modules from the target project. However, tr…
