Pipelines with scikit-learn Pipeline/ColumnTransformer — Roadmap Step…
Chaining preprocessing and modeling steps into a single, reusable object
- Level: advanced
- Estimated time: 1 days
- Roadmap: Machine Learning
Before this step
Mini projects
- Refactor a notebook's ad-hoc preprocessing and model steps into a single scikit-learn Pipeline
Interview questions
- Why does wrapping preprocessing in a Pipeline help prevent data leakage during cross-validation?
