Prepare modelled tabular data
Collect a representative tabular dataset, apply preprocessing and keep a held-out test set that reflects production input distributions.
Inspect partial dependence plots. Judge feature effects.
Partial dependence plots (PDPs) show how a single feature (or a pair) affects model predictions on average, holding other features marginally. They help detect non-linear effects, thresholds and interaction candidates, but can be misleading with correlated inputs or extrapolation beyond the training distribution.

Partial dependence plots (PDPs) show how a single feature (or a pair) affects model predictions on average, holding other features marginally. They help detect non-linear effects, thresholds and interaction candidates, but can be misleading with correlated inputs or extrapolation beyond the training distribution.
A proposed extension: an analyst-facing dashboard that surfaces PDPs and interaction plots so product managers can inspect suspected feature effects before changing model inputs or business rules. A human reviewer should remain in charge of decisions influenced by these visualisations.
Collect a representative tabular dataset, apply preprocessing and keep a held-out test set that reflects production input distributions.
Fit a well-tuned model (for example a RandomForest or gradient-boosted tree) and save it together with the feature pipeline.
Compute PDPs for key features and complementary diagnostics (ICE curves, interaction PDPs, SHAP summaries) and check effects against correlated features.
Expose interactive PDP charts, data filters and example instances so users can test and annotate surprising feature effects.
The supplied starter creates a synthetic binary classification dataset, trains a RandomForestClassifier, computes permutation-based feature importances, and prints the model score plus an importance table. It does not compute or plot partial dependence.
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 starter uses synthetic data from make_classification and computes permutation importance only; it does not calculate partial dependence plots or produce visualisations. Results on the synthetic 700-sample dataset do not validate behaviour on real tabular model data, and no diagnostics for correlated features or interactions are provided.
A proposed extension: replace the synthetic data with a real tabular model dataset, compute PDPs and ICE curves for selected features, add SHAP summaries and show interactive plots with instance-level filters so analysts can probe model behaviour.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
