YOLOR

YOLOR is a fine-tuned object detection model for BS identification for beam initialization to detect all five YOLOR custom classes — radio, 5G BS, LampPost, mmWave radio, streetlight — in one inference pass. The combined release model of the YOLOR detector family used for the Look Once, Beam Twice mmWave V2X beam-management pipeline (SECON 2026).

Usage

from huggingface_hub import hf_hub_download
from ultralytics import YOLO

weights = hf_hub_download(repo_id="cpnlab/YOLOR", filename="last.pt")
model = YOLO(weights)
results = model.predict("path/to/image.jpg", conf=0.25)

Class indices in returned detections:

• 0–79 — the 80 standard COCO classes
• 80 — radio
• 81 — 5G BS
• 82 — LampPost
• 83 — mmWave radio
• 84 — streetlight
