# Machine Learning Architecture

> A conceptual representation of a model's lifecycle as versioned data, feature, training, evaluation and serving stages.

Record: `architecture:machine-learning-architecture`
Kind: model
Layer: [Correctness Core](https://banes-lab.com/records/layer/correctness-core.md)
Severity: contextual
Scope: ML pipeline, model serving, data
Canonical: https://banes-lab.com/ontology#architecture-machine-learning-architecture

Listed in [Architecture principles](https://banes-lab.com/api/records/architecture.md), after [Artificial Intelligence Architecture](https://banes-lab.com/records/architecture/artificial-intelligence-architecture.md) and before [Model Governance](https://banes-lab.com/records/architecture/model-governance.md).

## Repair

- Refactored by: Add ML Pipeline, Version Data/Model/Config
- Detected by: missing lineage, untracked training inputs
- Violated by: unversioned data/model/config
- Measured by: [reproducibility](https://banes-lab.com/records/architecture/reproducibility.md), drift, evaluation metrics
- Enforced by: MLOps gates

## Requires

- [Data Pipeline](https://banes-lab.com/records/lexicon/data-pipeline.md)
