Data Augmentation's Effect on Machine Learning Models when Learning with Imbalanced Data

Damien A. Dablain;Nitesh V. Chawla

2024 IEEE 11th International Conference on Data Science and Advanced Analytics (DSAA)

Year: 2024 | Conference Paper |

Real-world data is often imbalanced, such that the number of training instances varies by class. Data augmentation (DA) of under-represented classes is commonly used to improve model generalization in the face of class imbalance. Despite its ubiquity, the impact of data augmentation on machine learning (ML) models is not clearly understood. Here, we undertake a holistic examination of the effect o...Show More

Deep learning models may not effectively generalize across under-represented or minority classes. We empirically study a convolutional neural network’s (CNN) internal representation of imbalanced image data and measure the generalization gap between a model’s feature embeddings in the training and test sets, showing that the gap is wider for minority classes. This insight enables us to design an e...Show More
