Discriminant Analysis is a powerful tool for understanding and predicting the relationships between variables
To implement a custom loss function in scikit-learn, we'll need to use the make_scorer function
Use XGBoost in Python via its scikit-learn API (XGBClassifier/Regressor) or native DMatrix API. Key hyperparameters and early stopping explained.
fit vs transform vs fit_transform in scikit-learn, and the rule that prevents data leakage: fit on train only, transform train and test with the training parameters. Plus why a Pipeline is the correct way to enforce this.
StratifiedKFold makes k non-overlapping folds (every sample tested once); StratifiedShuffleSplit draws independent random splits. When to use each.
