Comparative Analysis of Data Augmentation for Clinical ECG Classification with STAR

2025-10-24

Abstract excerpt

Clinical 12-lead ECG classification remains difficult because of diverse recording conditions, overlapping pathologies, and pronounced label imbalance hinder generalization, while unconstrained augmentations risk distorting diagnostically critical morphology. In this study, Sinusoidal Time–Amplitude Resampling (STAR) is introduced as a beat-wise augmentation that operates strictly between successive R-peaks to app...
