Required inputs

A compatible model and representative inputs; some explanation and faithfulness methods also require labels or task-specific reference regions.

Test procedure

Generate the explanation with recorded method settings. Inspect representative and difficult cases, and use an applicable faithfulness check where available.

Interpreting results

Use the explanation to investigate which inputs influence a prediction and whether that account remains consistent with the model's behaviour.

Limitations

Evidence record

Preserve the input, prediction, explanation, method configuration and any faithfulness results used in the review.
