Prepare tabular data and splits
Assemble a representative labelled dataset, perform feature cleaning, and keep a held-out test set for explanation stability checks.
Build a SHAP explanation dashboard. Inspect feature-level contributions.
A SHAP explanation dashboard visualises per-feature contributions for individual tabular predictions so users can audit and interrogate model decisions. Key challenges include selecting representative background samples for SHAP values, handling correlated features, keeping explanations stable over time, and presenting explanations so non-technical reviewers can act on them.

A SHAP explanation dashboard visualises per-feature contributions for individual tabular predictions so users can audit and interrogate model decisions. Key challenges include selecting representative background samples for SHAP values, handling correlated features, keeping explanations stable over time, and presenting explanations so non-technical reviewers can act on them.
A proposed application: an auditor-facing dashboard that surfaces SHAP explanations alongside model predictions so domain experts can accept, flag or annotate individual decisions before they affect users. This prototype should keep a human reviewer in the loop; it is not suitable for automated high-risk decisions without further validation.
Assemble a representative labelled dataset, perform feature cleaning, and keep a held-out test set for explanation stability checks.
Fit a robust classifier with a fixed random seed and log parameters so explanations can be compared across versions.
Use a SHAP explainer appropriate for your model (TreeExplainer for tree ensembles) and choose an interpretable background dataset.
Visualise per-instance SHAP contributions, run explanation-stability and counterfactual checks, and collect curator feedback.
The supplied starter generates a synthetic classification dataset, trains a RandomForestClassifier, computes permutation-based feature importances on the test set, and prints the model score and a sorted importance table. It does not compute or display SHAP values or 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})
report = report.sort_values("importance", ascending=False)The starter uses synthetic data from sklearn.make_classification and computes permutation_importance rather than SHAP values; it therefore does not implement the titled SHAP dashboard or demonstrate SHAP-specific behaviours (background selection, per-instance attributions, or TreeExplainer optimisations). The synthetic dataset and small test set also prevent conclusions about real-world explanation stability.
Proposed extension: replace the synthetic data with a real tabular dataset, compute per-instance SHAP values (TreeExplainer for tree models), and surface them in an interactive dashboard that lets auditors filter by feature attribution and record feedback.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
