Prepare the data
Use a labelled toy set and create a separate controlled label-noise experiment.
Reweight mistakes. Track the next learner.
AdaBoost sequentially emphasises examples earlier learners misclassify. Weak learners, estimator weights and sensitivity to noisy labels are useful points of comparison with bagging.

A possible application for ml instructors: Provide an interactive classroom explanation of adaptive boosting. This extension is not delivered by the supplied starter.
Use a labelled toy set and create a separate controlled label-noise experiment.
Fit AdaBoostClassifier with shallow decision trees and inspect staged predictions.
Compare held-out error across boosting rounds and measure sensitivity to label noise.
Display staged error curves and the weights assigned to weak learners.
The supplied starter creates 800 synthetic binary-classification rows with ten numeric features. It makes a stratified train/test split, fits a scaled RandomForestClassifier pipeline and prints a classification report.
model = Pipeline(
steps=[
("scale", StandardScaler()),
("classifier", RandomForestClassifier(
n_estimators=250, random_state=RANDOM_STATE)),
]
)
model.fit(X_train, y_train)
predictions = model.predict(X_test)
print(classification_report(y_test, predictions))The supplied estimator is a random forest, not AdaBoost, and has no adaptive reweighting stages. Synthetic binary classification does not establish performance on the proposed application. The source report uses one split; it supplies no deployment or real-world validation.
Proposed extension: Provide an interactive classroom explanation of adaptive boosting.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
