featuresmanuscript

The term featuresmanuscript refers to a documentation artifact used in data science and machine learning projects to describe, explain, and archive the features used by a predictive model. It serves as a stable reference that complements code, notebooks, and model artifacts, aiding reproducibility and collaboration.

A featuresmanuscript typically includes structured metadata for each feature. Common elements are the feature name, type (numeric, categorical, boolean, text), description, data source, calculation method or feature engineering steps, handling of missing values, encoding or transformation, and the feature’s expected range or distribution. It often records feature lineage, dependencies on data pipelines, and version history to track how features evolve over time. Governance fields such as owner, approval status, privacy considerations, and access restrictions may also be included.

The benefits of maintaining a featuresmanuscript include improved reproducibility and auditability, easier model governance, and clearer communication among data scientists, engineers, and business stakeholders. It supports feature re-use across models, simplifies debugging when features behave unexpectedly, and aids drift monitoring by documenting the intended behavior of each feature.

Creation and maintenance can be manual or automated. Templates or forms help standardize entries, while feature stores and data catalog tools can generate portions of the manuscript or export metadata. A well-maintained featuresmanuscript aligns with version control practices and integrates with data lineage and privacy compliance workflows, reducing ambiguity when features are updated or reused.

Challenges include keeping the manuscript up to date as data pipelines change, managing drift, ensuring consistency across teams, and balancing detail with usability. Clear ownership and governance processes help mitigate these issues.
