Training Sets

Brain training reference images organized by domain. All images are CC0 / public domain.

Directory Structure

training_sets/
├── sunsets/       ← SKY domain: sunset, golden hour, sky gradients
├── oceans/        ← SEA domain: ocean, waves, coastal
├── food/          ← FOOD domain: food photography, plating
├── portraits/     ← PORTRAIT domain: people, faces, characters
├── urban/         ← URBAN domain: city, architecture, streets
├── nature/        ← NATURE domain: mountains, forests, landscapes
└── weather/       ← WEATHER domain: fog, rain, snow, storms

Usage

From the ralpha repo:

# Run batch training on a domain
python -m brain.batch --dir /path/to/ralpha-ue5/training_sets/sunsets/ \
  --domain SKY --llm gemini --max-iterations 20 --shuffle

# Or symlink for convenience
ln -s /path/to/ralpha-ue5/training_sets ~/ralpha/training_sets

Sourcing Images

# Download CC0 sunset images (PxHere, with EXIF)
cd /path/to/ralpha
python scripts/dev/download_training_sunsets.py --output /path/to/ralpha-ue5/training_sets/sunsets/

EXIF Data

Images with intact EXIF are preferred — the brain extracts:

• Camera model + lens → locks CineCamera focal length, aperture
• Date/time → computes exact sun position via ephemeris
• GPS → loads Cesium tiles for that location, locks sun azimuth
• ISO/aperture/shutter → exposure starting point

Images without EXIF still work — the brain uses VLM analysis to estimate scene parameters.

Licensing

All images in this directory must be CC0 (Creative Commons Zero) or public domain. The manifest.json in each subdirectory records the source and license of each image.
