What this module covers

This is the finale of the numbered curriculum — the notebook that ties everything together. You've learned the pieces: preparing data (47), classifying (48), clustering (49).

By the end of it

  • Execute the full ML lifecycle: frame → prepare → select → tune → evaluate → interpret → persist
  • Build one leak-free Pipeline combining preprocessing (ColumnTransformer) and a model
  • Compare candidate models with cross-validation, then tune the winner with GridSearchCV / RandomizedSearchCV
  • Diagnose fit with learning curves and validation curves
  • Perform the final, single evaluation on held-out data and interpret it (metrics, confusion matrix, feature importance)
  • Save and reload a trained pipeline with joblib for reuse/deployment
  • Structure a project so that data leakage is impossible from start to finish
