Dream-Cubed Natural Representative Sample

This directory is a deterministic, class-stratified sample of the Dream-Cubed Natural dataset. It is provided for reviewer inspection of data quality; the full dataset remains available at https://huggingface.co/datasets/dream-cubed/DreamCubedNatural.

The sample dataset for human-authored data is available at https://huggingface.co/datasets/dream-cubed/DreamCubedHumanSample

The sample includes raw natural biome chunks and processed train/validation examples.

Creation Procedure

• Sampling seed: 67
• Last source mode added: raw
• Raw target: up to 32 chunks per raw source label
• Processed target: up to 128 chunks per label per split
• Strategy: deterministic stratified sampling without replacement
• Output: compact .npz raw samples and restored, unsharded processed .npy split samples

Exact source paths, selected source indices, sample counts, and output files are recorded in sample_manifest.json. Processed split directories also include source_indices.npy and fresh manifest.json files. Dataset metadata files copied from nearby public dataset files are stored under metadata/ when available.

Inspection Notes

This sample is intentionally small and should not be used for model training or quantitative evaluation. It is meant only to help reviewers inspect file formats, labels, chunk tensors, and overall data quality without downloading the full multi-GB dataset.
