Define the drift task
Decide whether you monitor covariate drift, label shift or concept drift and choose appropriate metrics and alert thresholds.
Explain dataset drift. Prioritise investigation.
A drift explanation dashboard helps teams detect distributional changes and show which features caused the shift. Useful diagnostics include population stability, PSI, feature-wise importance changes and local explanations; common failure modes are population shifts that do not affect accuracy, correlated feature drift and missing-data patterns.

A drift explanation dashboard helps teams detect distributional changes and show which features caused the shift. Useful diagnostics include population stability, PSI, feature-wise importance changes and local explanations; common failure modes are population shifts that do not affect accuracy, correlated feature drift and missing-data patterns.
A proposed use: run continuous checks on model inputs and produce human-reviewable explanations for alerts so operations teams can decide whether to retrain, investigate data collection or roll back a deployment. This starter does not deliver an interactive dashboard or drift detectors — it is a foundation for those extensions.
Decide whether you monitor covariate drift, label shift or concept drift and choose appropriate metrics and alert thresholds.
Assemble a clean reference set and a stream or batch of current data; align schemas and handle missing features before comparison.
Measure univariate and multivariate drift (PSI, KS, classifier two-sample tests) and track feature importance shifts over time.
Present top contributing features, example-level explanations and contextual metadata so a human can assess cause and action.
The supplied starter creates a synthetic classification dataset with sklearn.make_classification, fits a RandomForestClassifier on a single train/test split, computes permutation feature importances on the test set and prints the model score plus a small importance table. It does not simulate or detect dataset drift nor produce a dashboard.
X, y = make_classification(n_samples=700, n_features=8, n_informative=5, random_state=42)
columns = [f"feature_{i}" for i in range(X.shape[1])]
X = pd.DataFrame(X, columns=columns)
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.25, random_state=42, stratify=y)
model = RandomForestClassifier(n_estimators=250, random_state=42)
model.fit(X_train, y_train)
importance = permutation_importance(model, X_test, y_test, n_repeats=10, random_state=42)
report = pd.DataFrame({"feature": columns, "importance": importance.importances_mean})The code uses a single synthetic dataset and one train/test split; it does not simulate time or distributional shifts, does not compute drift metrics, does not produce per-period comparisons, and does not build a dashboard or alerting. Feature importance on a static test set is not an explanation of drift.
A proposed extension is to log incoming data batches, compute per-batch drift metrics (PSI, KS, two-sample classifier AUC), compare feature importances across periods (permutation or SHAP), and expose these signals in a simple web dashboard with human-review actions (annotate, mute, retrain).
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
