# Dream-Cubed Human Representative Sample

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

The sample dataset for procedurally generated data is available at https://huggingface.co/datasets/dream-cubed/DreamCubedNatural.


Depending on which commands have been run, the sample may include raw human-authored map chunks and/or compact processed train/validation examples. Processed examples may also contain natural biome chunks from the companion Dream-Cubed Natural release. Permission to release voxelized chunks from the human-authored maps was granted explicitly by the anonymized map creator for noncommercial research, but not for commercial products or reconstruction of the original maps.

## 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.
