Breast cancer classification using deep learning architectures plays a crucial role in assisting clinicians with early-stage diagnosis. In this study, we present a comprehensive evaluation of YOLO architectures-YOLOv2, YOLOv3, YOLOv4, and YOLOv5-for the classification of breast lesions in thermal breast images. By employing these architectures, we...
