    Class-Balanced Random Patch Training to Address Class Imbalance in Tiling-Based Farmland Classification by Yeongung Bae, Yuseok Ban

    Published 2025-06-01
    “…Additionally, farmland classification frequently exhibits class imbalance due to uneven cultivation areas, resulting in biased training toward majority classes and poorer performance on minority classes. To overcome these issues, we propose Class-Balanced Random Patch Training, which combines Random Patch Extraction (RPE) and Class-Balanced Sampling (CBS). …”
