| # Building Footprint Extraction — FootprintNet checkpoints |
|
|
| Checkpoints for the BONAI building-footprint extraction project. Each folder holds the best |
| checkpoint for one model run. The model family lineage is V0–V3 (ResNet-50 base), V4-Attention |
| (RegNetY-6.4GF), V5-Attention (18-channel pruned), and V6 (SegFormer mit_b2) which is the current |
| family. |
| |
| ## Current best model: v6_8ch |
|
|
| | File | Description | |
| |------|-------------| |
| | `v6_8ch/best_v6_8ch.pt` | Best checkpoint, 8 input channels, mIoU **0.5249** (TTA 0.5317) | |
| | `v6_8ch/best_v6_8ch_stripped.pt` | Deployable stripped weights (inference only) | |
| | `v6_8ch/eval_summary.txt` | Held-out eval metrics | |
| | `v6_8ch/tta_summary.txt` | HFlip+VFlip TTA comparison | |
|
|
| Best config: `in_channels=8`, SegFormer `mit_b2`, `batch_size=24`, `accum_steps=2`, `lr=3e-5`, |
| `warmup_epochs=8`, `early_stop_patience=30`, `grad_checkpoint=true`, `amp=true`. |
