Foliage Hunter Experiments

Held-out methodology, split manifests, and metrics for the EdyVision/foliage-hunter-gemma3-12b LoRA adapter (adapters/colorado_v1), the model behind Foliage Hunter.

Project repo, app, training and serving code: https://github.com/EdyVision/foliage-hunter
Adapter: https://huggingface.co/EdyVision/foliage-hunter-gemma3-12b
Base model: https://huggingface.co/google/gemma-3-12b-it

The CC BY 4.0 license on this dataset covers the metadata, manifests, and results published here. It does not relicense the underlying iNaturalist photos, which keep their own per-photo licenses (see below).

Important: no image bytes

This dataset publishes metadata only (observation IDs, licenses, species, split membership, eval predictions). The photos include NC and ND material and are not redistributed. Rebuild them with training/scripts/build_inat_corpus.py from the repo against colorado_v1/*_manifest.jsonl.

Layout

colorado_v1/
  METHODOLOGY.json          # train/eval protocol
  train_manifest.jsonl      # 1152 rows (observation_id, species, license, ...)
  eval_manifest.jsonl       # 288 rows
  eval_results.json         # per-image generate-and-match outcomes

Manifest row fields: observation_id, species, scientific, tier, inat_taxon_id, license, image_relpath.

Held-out result

Metric	Value
n	288
hits	245
accuracy	85.1%
matching	case-insensitive exact / substring on common name

Stratification: every 5th image per species to eval (~20%).

Source data and attribution

Every photo referenced here is a research-grade observation photo contributed by an iNaturalist user and retrieved through the public iNaturalist API. 1,440 photos from 729 observations across 18 species (80 photos per species; Colorado place_id=34 filter for the local tiers). Species list in colorado_v1/colorado_priority_species.json.

Per-photo licenses in the corpus:

The photos were used for private model training and evaluation only. To credit an individual photographer, open https://www.inaturalist.org/observations/<observation_id> for any row in the manifests; the observer's name and the photo license are shown there.

Thank you to the iNaturalist observers whose photos taught the model what a Colorado leaf looks like.
