The most common form in notebooks is preprocessing the whole dataset (scaling, imputing missing values, encoding categories) with pandas before splitting it, so the model has already seen statistics from the rows it is tested on. Put every preprocessing step inside a scikit-learn Pipeline and pass that pipeline to cross-validation, so each fold fits its preprocessing on its own training part only. The other form is a feature that wouldn't exist at prediction time, such as a status column filled in after the outcome; check each feature's timing before trusting a surprisingly good score.",{"question":334,"answer":335},"Should I use scikit-learn's gradient boosting or XGBoost and LightGBM?","Start with scikit-learn's HistGradientBoostingClassifier or Regressor. It uses the same histogram-based approach that made LightGBM fast, handles missing values without imputation, and fits into Pipelines and cross-validation like every other estimator. XGBoost and LightGBM are worth installing when you need GPU training, very large datasets, or tuning options scikit-learn doesn't expose. Both provide scikit-learn-compatible estimator classes, so swapping later is a one-line change in the pipeline.",{"question":337,"answer":338},"How do I use a trained model outside the notebook?","Save the whole fitted Pipeline, not only the model, so the same preprocessing runs on new data. joblib is the usual way; skops is an alternative whose format can be inspected before loading, which is safer for files from other people.
