Akopọ
An explanation describes model behavior under a chosen background and feature-dependence setup; it is not automatically causal or legally sufficient.
Jin Dive
SHAP methods use Shapley-value concepts to allocate a prediction among features. TreeSHAP provides efficient exact calculations for supported tree ensembles. Explanations depend on the model, reference distribution, feature-dependence assumptions, and output scale. A contribution indicates how the model output changes under that method; it does not establish that a feature caused the outcome, that the model is fair, or that an explanation satisfies a legal duty.

Interpretability methods can support debugging and auditing when assumptions are disclosed. Combine them with performance, subgroup, causal, and domain analyses; do not present SHAP as a standalone fairness or compliance test.

Kini Apejuwe AI ati SHAP?
SHAP assigns feature contributions to a model prediction using Shapley-value ideas. An explanation describes model behavior under a chosen background and feature-dependence setup; it is not automatically causal or legally sufficient.

Why do teams use explanation methods such as SHAP during model development?
SHAP can help inspect a model’s predictions, but legal duties vary and attribution does not establish causality or fairness.
What can a SHAP summary plot show across a dataset?
SHAP documentation describes summary plots as showing feature impact across instances; plotted SHAP values display the range and distribution of those effects.
