# Foliage Hunter Experiments

Held-out methodology, split manifests, and metrics for the
[`EdyVision/foliage-hunter-gemma3-12b`](https://huggingface.co/EdyVision/foliage-hunter-gemma3-12b)
LoRA adapter (`adapters/colorado_v1`), the model behind
[Foliage Hunter](https://github.com/EdyVision/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`](https://github.com/EdyVision/foliage-hunter/blob/main/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
  colorado_priority_species.json
  manifest.json
```

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](https://api.inaturalist.org/v1/docs/). 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:

| License | Photos |
|---------|-------:|
| CC BY-NC | 1016 |
| CC BY | 301 |
| CC0 | 47 |
| CC BY-NC-ND | 38 |
| CC BY-NC-SA | 28 |
| CC BY-ND | 6 |
| CC BY-SA | 4 |

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.
