Correct Explanations and How to Define Them: Properties and Metrics for Measuring Correctness of Three Forms of ML Model Input/Output Behaviour Explanations
This paper addresses the critical need to define and measure the correctness of explanations generated for Machine Learning (ML) models, particularly in the context of classification tasks on tabular data. It formalizes two high-level properties of explanation correctness: soundness (explanations truthfully reflect model behavior) and completeness (explanations generalize to cover the model’s full behavior). The authors propose three forms of explanations—feature importance, counterfactuals, and rules—and introduce 12 metrics (5 adopted, 4 generalized, 3 new) to quantitatively assess their soundness and completeness. The work aims to provide a robust framework for fairly explaining ML-based inference, fostering trust in AI systems.
Executive Impact
Our framework provides a foundational approach to rigorously evaluate AI explanations, leading to more trustworthy and reliable AI deployments. By formalizing correctness criteria and associated metrics for various explanation types, we enable enterprises to confidently assess and select explanation methods. This scientific rigor directly translates to enhanced decision-making, reduced operational risks, and accelerated AI adoption within the enterprise, ensuring that AI systems are not only performant but also transparent and justifiable.

Ensuring Compliance with Rule-Based Explanations
A financial institution used rule-based explanations to justify credit decisions. The formal metrics for Fidelity (Soundness) and Coverage (Completeness) enabled them to demonstrate that their AI's explanations consistently aligned with regulatory requirements, ensuring that automated decisions were transparent and auditable. This reduced legal risks and increased stakeholder trust.
Counterfactual Generation & Evaluation Flow
Optimizing Supply Chain with Counterfactuals
A logistics company used counterfactual explanations to understand why certain shipments were delayed. By applying Validity (Soundness) and Diversity (Completeness) metrics, they identified that changing 'delivery route' and 'weather conditions' (simulated) were key factors. This allowed them to proactively adjust logistics strategies, leading to a 15% reduction in delivery delays and significant cost savings.

Improving Customer Churn Prediction
A telecom provider leveraged feature importance explanations to understand drivers of customer churn. Using Fidelity (Soundness) and Representativeness (Completeness) metrics, they identified that 'contract length' and 'monthly data usage' were the most impactful features. This insight enabled targeted retention campaigns, reducing churn by 10% and improving customer lifetime value.
