Researchers have developed a new method called Generative Defect Isolation (GDI) to improve the classification of multiple defects in photovoltaic modules. GDI uses the LaMa inpainting model with Fast Fourier Convolutions to generate realistic training samples with single defects, addressing the challenge of learning ambiguity and data scarcity in multi-label defect classification. Experiments show that GDI significantly enhances the performance of Vision Transformer and EfficientNetV2-L architectures, particularly in low-data scenarios, leading to substantial F1-Score improvements for rare defect classes and a reduction in classification errors for co-occurring defects.
