Explainable AI (XAI) Services

A model that predicts well but cannot be explained is hard to trust, publish, or act on. Explainable AI opens the black box—showing which features drive predictions and how—so complex models become interpretable. MAS Research applies SHAP and related methods to make machine-learning results transparent, and does so without overclaiming what an explanation means.

Explainable AI (XAI) is a set of techniques for understanding how a machine-learning model makes its predictions. Methods such as SHAP, feature importance, and partial-dependence plots reveal which inputs matter and how they affect the output, both overall and for individual predictions. XAI explains the model’s behaviour—which is not the same as establishing causal effects in the real world.

What explainable AI does

The most accurate predictive models—gradient-boosted trees, deep neural networks—are often the least transparent. They can forecast well while giving no obvious account of why, which is a problem when results must be trusted by reviewers, understood by decision-makers, or defended in a regulated setting. Explainable AI (XAI) addresses this by providing principled ways to interpret an otherwise opaque model: to see which inputs drive its predictions, in what direction, and by how much.

XAI works at two levels. Global explanations describe the model as a whole—which features matter most across all cases—through feature-importance measures and partial-dependence or accumulated-local-effects plots that show the shape of a feature’s influence. Local explanations account for a single prediction—why this applicant was scored as high-risk, why this case was flagged—through methods such as SHAP (Shapley additive explanations), which fairly attributes a prediction to its contributing features, and related approaches like LIME. Together they turn a black box into something a researcher or practitioner can inspect and reason about.

When to use it—and what it does not mean

Use XAI whenever a complex model’s predictions need to be understood, justified, or communicated: to satisfy reviewers who want to know what a model learned, to give decision-makers confidence, to debug a model and detect spurious patterns, or to meet transparency expectations. It is also valuable in hybrid econometric-ML work, where flexible ML is combined with interpretable modelling to get both performance and insight.

One caution is essential, because it is where XAI is most often misread: an explanation describes the model, not the world. SHAP values and feature importances show what drives the model’s predictions—associations the model has learned, confounding and all—not the causal effect of changing a variable. A feature can be highly “important” to a prediction while having no causal relationship to the outcome. If the question is causal, that calls for causal machine learning or a causal-inference design. We make this boundary explicit, so an explanation is never mistaken for a causal finding.

Methodology

Explaining models responsibly

Good XAI is more than running a SHAP plot. The method should fit the model and the question: SHAP has strong theoretical properties (it is grounded in Shapley values from cooperative game theory and attributes a prediction fairly across features), with efficient implementations for tree models; partial-dependence and accumulated-local-effects plots reveal effect shapes but can mislead when features are strongly correlated, so they are read with care. We choose and combine techniques deliberately, and interpret them in light of their assumptions rather than treating any single plot as the final word.

Two cautions shape responsible practice. First, explanations can be unstable or misleading if applied carelessly—correlated features can share or distort attributions, and some methods are sensitive to how they are configured—so we check robustness rather than presenting one plot uncritically. Second, and most importantly, we hold the line between explanation and causation: feature attributions are statements about the model, and we present them as such. Where the goal is genuine insight into mechanisms, we turn to hybrid econometric-ML designs that pair ML’s flexibility with interpretable, theory-grounded structure.

An explanation describes the model, not the world. SHAP values and feature importances show what drives the model’s predictions—learned associations, confounding included—not the causal effect of changing a variable. A feature can be highly important yet have no causal link to the outcome.

Software

We deliver XAI in established, reproducible tools—Python (shap, scikit-learn, interpret, alibi) and R—providing global and local explanations (SHAP, feature importance, PDP/ALE), robustness checks, and clear visualisations, alongside hybrid econometric-ML modelling where interpretability and performance are both needed, all with versioned code.

How we work

How we deliver an explainability analysis

XAI sits within our wider machine-learning practice—so explanations fit the model, are checked for robustness, and are never overstated as causal.

We start from the model and the purpose of the explanation—understanding, validation, communication, or auditing individual decisions—and choose the techniques that fit. We produce global explanations (what drives the model overall) and local ones (why specific predictions), check that attributions are stable and sensible given feature correlations, and present them in clear, interpretable visualisations.

Reporting sets out the explanation methods and why they were chosen, the global and local findings, the robustness checks, and—explicitly—the boundary between explaining the model and claiming causation.

You receive the model explanations (SHAP and complementary analyses), global feature-driver summaries and per-case local explanations where relevant, robustness checks, clear visualisations for a research or decision audience, and reproducible analytical code and analysis-ready files (where appropriate and permitted)—with the explanation-not-causation boundary stated plainly.

FAQ

Explainable AI: common questions

Explainable AI (XAI) is a set of techniques for understanding how a machine-learning model makes its predictions. Methods such as SHAP, feature importance, and partial-dependence plots reveal which inputs matter and how they affect the output—both globally (across all cases) and locally (for individual predictions). It makes otherwise opaque models interpretable, which matters for trust, publication, debugging, and accountability.
SHAP (Shapley additive explanations) is a widely used XAI method grounded in Shapley values from cooperative game theory. It fairly attributes a model’s prediction across its input features, showing how much each feature pushed the prediction above or below a baseline. SHAP provides both local explanations (for individual predictions) and global summaries (aggregated across cases), and has efficient implementations for tree-based models.
Global explanations describe the model as a whole—which features matter most across all cases and the general shape of their effects—using feature importance and partial-dependence or ALE plots. Local explanations account for a single prediction, showing why one specific case received the score it did, typically with SHAP values or LIME. Global explanations help you understand and validate a model; local ones help justify or audit individual decisions.
No. A SHAP value shows how much a feature contributed to the model’s prediction—an association the model has learned, confounding included—not the causal effect of changing that feature in the real world. A feature can be highly important to a prediction without being a cause of the outcome. For causal questions, a causal-inference design or causal machine learning is required; XAI explains the model, not the world.
They must be interpreted with care. When features are strongly correlated, importance and attribution can be shared or distorted between them, and some methods are sensitive to configuration. Partial-dependence plots can also mislead under correlation. We choose methods suited to the model, check that explanations are stable, and interpret them in light of their assumptions rather than presenting a single plot as definitive.
Hybrid econometric-ML approaches combine the flexibility of machine learning with the interpretability and theoretical grounding of econometric modelling—for example, using ML to capture complex nuisance components while retaining an interpretable, theory-driven parameter of interest. They aim to get strong performance without wholly sacrificing insight, and are useful when both prediction quality and interpretability matter.
