Best overall model in the suite. ## Metrics — RDD held-out validation (4,509 images, 11,470 boxes) | Class | mAP@50 | mAP@50-95 | Precision | Recall | F1 | |---|---:|---:|---:|---:|---:| | D00 Longitudinal | 0.635 | 0.357 | 0.720 | 0.561 | 0.630 | | D10 Transverse | 0.664 | 0.345 | 0.715 | 0.589 | 0.646 | | D20 Alligator | 0.727 | 0.409 | 0.743 | 0.647 | 0.692 | | D40 Pothole | 0.741 | 0.390 | 0.774 | 0.668 | 0.717 | | **Overall** | **0.692** | **0.375** | **0.738** | **0.616** | **0.672** | ## Full model comparison (same held-out val) All five models in this study, evaluated identically (imgsz 640): | Model | Variant | Params | Distillation | mAP@50 | mAP@50-95 | F1 | |---|---|---:|---|---:|---:|---:| | [YOLO26n_RDD_Base](https://huggingface.co/TamAko783/YOLO26n_RDD_Base) | YOLO26n | 2.4M | — (GT only) | 0.635 | 0.334 | 0.621 | | [YOLO26n_RDD_FRDC_Distilled](https://huggingface.co/TamAko783/YOLO26n_RDD_FRDC_Distilled) | YOLO26n | 2.4M | 1 teacher (Co-DETR) | 0.640 | 0.337 | 0.625 | | [YOLO26n_RDD_FRDC_Distilled_v2](https://huggingface.co/TamAko783/YOLO26n_RDD_FRDC_Distilled_v2) | YOLO26n | 2.4M | 2 teachers (Co-DETR+RTMDet) | 0.638 | 0.337 | 0.626 | | [YOLO26s_RDD_Base](https://huggingface.co/TamAko783/YOLO26s_RDD_Base) | YOLO26s | 9M | — (GT only) | 0.687 | 0.372 | 0.665 | | **➤ YOLO26s_RDD_FRDC_Distilled_v2** (this model) | YOLO26s | 9M | 2 teachers (Co-DETR+RTMDet) | **0.692** | **0.375** | **0.672** | **Reading it:...
