betaearth-dinov3-vits16

BetaEarth DINOv3 ViT-S/16 (natural pretrained, frozen) — lightweight

Metric	Value
Test cosine similarity	0.861
LULC downstream accuracy	0.863
Trainable parameters	1.8M
Total parameters	23.8M (backbone loaded from torch.hub)
Inputs	6 spectral primitives + DOY

Note: This repo contains only the trainable weights (DPT head, FiLM, fusion, decoder — 1.8M). The frozen DINOv3 backbone is loaded from via at runtime.
