dinov2-small-fire-associated-smoke-v2.5

모델 소개

Binary **fire-associated smoke compatibility**, not smoke-source pointing or physical aerosol density. A probable-fire ROI with no confirmed visible flame can be routed here. Input: RGB crop with 45% context per side, minimum side 160, bicubic 448×448 resize and ImageNet normalization. DINOv2 ViT-S/14 CLS embedding (384) → LayerNorm → dropout 0.15 → linear logit. Output is temperature-scaled compatibility with a low/high decision and an abstention interval. Rejected smoke keypoints, masks and spatial-refiner runs are not included. Positive labels require retained provenance supporting fire-associated smoke or visible flame elsewhere in the source image. Crops containing a flame fragment are excluded, as are unsupported associations; ambiguous is an inference abstention state, not a third training label. Training membership is not gated by another model's predicted absence of flame. Linked v2.5-smoke-from-fire-probability: 50,183 train / 12,106 validation public ROIs, a rights-filtered subset of the retained full run corpus. Run `20261005-075018-dinov2_vits14`: 3 head-only epochs then 5 epochs with the last two backbone blocks unfrozen, batch 48, BF16, seed 42. Head LR 3e-4, backbone LR 5e-6, weight decay 0.05, 0.5-epoch warmup and cosine decay per phase. Best checkpoint is tail phase **E3 (overall E6)** by selection-fold AUPRC. Eight epochs completed. Official DINOv2 source is pinned at `7764ea0f912e53c92e82eb78a2a1631e92725fc8`.
