Data Preprocessing Pipeline

Positioning

Use this skill as the direct owner for ML input-preparation pipelines.

It covers preprocessing-heavy tasks where the requested deliverable is a repeatable pipeline for cleaning, encoding, transforming, and validating input data.

When to Use

Use this skill when:

• Prepare raw data for machine learning models.
• Automate data cleaning and transformation processes.
• Implement a robust ETL (Extract, Transform, Load) pipeline.

Not For / Boundaries

• Whole-task ML ownership: use scikit-learn or ml-pipeline-workflow
• Leakage and prediction-time auditing: use ml-data-leakage-guard
• Grouped scientific preprocessing with stronger methodological constraints: use scientific-data-preprocessing

Typical Outputs

• A preprocessing pipeline plan or implementation sketch
• Clear sequencing for clean, encode, transform, and validate steps
• Notes that identify where leakage review, training, or evaluation should be run next
