Reproducibility means recreating a dataset from scratch using the same source and a documented software procedure. Replace manually crafted “golden” files with a script, pipeline, or larger system that collaborators can run. section 6.6
A reproducible data workflow should:
- Record the origin and preprocessing steps needed to regenerate the dataset. section 6.6
- Test the regeneration procedure so every project collaborator can run it. section 6.6
- Treat dataset construction like infrastructure as code rather than a one-time manual task. section 6.6
- Preserve metadata and ensure the pipeline also remains consistent and available. section 6.8
The missed preprocessing step
A manually assembled dataset may work initially, but a later batch can omit one preprocessing step. Regenerating the data through a tested procedure makes that omission less likely and easier to detect before it affects system performance. section 6.6
Reproducibility supports maintainable dataset updates, while consistency addresses whether labels and other data properties follow stable rules. Both matter when preparing data for machine learning. section 6.6 section 6.8
