PCB-Prune-YOLO P20 Direct
Validation-selected YOLOv8n checkpoint produced by direct DepGraph structured
pruning followed by 50-epoch matched fine-tuning on DeepPCB. No sparse learning,
knowledge distillation, or test-set model selection was used.

The model has 1,913,971 parameters and 2.5722 GMACs, reductions of 36.46% and
36.85% from baseline. Its static batch-1 TensorRT FP16 engine reaches 1.933 ms
(517.45 FPS) on Tesla T4 with validation mAP50-95 0.76931.
Training used direct local group-magnitude pruning at ratio 0.20 without channel
rounding, followed by AdamW (lr0=0.001, lrf=0.01, weight decay 0.0005),
batch 64, patience 10, seed 42, AMP, and deterministic mode.
Structured pruning changes the architecture. Clone and install the
