Training Reproducibility Guide
Agent Prompt Snippet
Document all random seeds, library versions, hardware specifications, and hyperparameters needed to fully reproduce the model training process.Purpose
A reproducibility guide records random seeds, library versions, hardware specs, and hyperparameters so that any engineer can reproduce training results from scratch.
This is a Recommended document — most projects benefit significantly from having one. While not strictly essential for every situation, its absence often leads to gaps in team understanding or quality.
Key Sections to Include
- All random seeds
- Library versions
- Hardware specifications
- Hyperparameters needed to fully reproduce the model training process
Agent hint: Document all random seeds, library versions, hardware specifications, and hyperparameters needed to fully reproduce the model training process.
What Makes It Good vs Bad
A strong version of this document:
- Documents model architecture, training data, and evaluation metrics clearly
- Includes bias analysis and fairness considerations
- Specifies model versioning, A/B testing, and rollback procedures
- Defines monitoring for model drift, data drift, and performance degradation
- Connects model decisions to business outcomes with measurable criteria
Warning signs of a weak version:
- Only documents final model — no record of experiments or alternatives tried
- Missing bias and fairness analysis for the training data and predictions
- No monitoring strategy for production model performance
- Training pipeline undocumented — impossible to reproduce results
- No clear process for model updates, retraining triggers, or deprecation
Common Mistakes
- Not documenting the training data provenance and preprocessing steps
- Skipping fairness and bias analysis — assuming the data is representative
- Deploying models without monitoring for performance degradation over time
- Treating model training as a one-time event rather than a recurring process
How to Use This Document
Document the full ML lifecycle: data collection, preprocessing, feature engineering, model selection, training, evaluation, deployment, and monitoring. Record experiment results even for failed approaches — they prevent future teams from repeating dead ends. Define clear criteria for when a model should be retrained or retired.
For AI agents: Reference ML documentation to understand model behavior, training data characteristics, and known limitations. When modifying ML pipelines, verify changes against documented evaluation metrics and fairness criteria.
