SHAP assigns feature contributions to a model prediction using Shapley-value ideas.
Dengar panduan iniAI-diceritakan · ~1 min
An explanation describes model behavior under a chosen background and feature-dependence setup; it is not automatically causal or legally sufficient.
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.
Inspect feature contributions for a particular prediction.
Compare contribution distributions across a dataset.
Check how correlated features affect attribution.
Document model, background data, and explanation settings.
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.

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.
SHAP menyesuaikan nilai Shapley, yang mengagihkan 'pembayaran' (ramalan) secara adil di kalangan 'pemain' (ciri input) berdasarkan sumbangan mereka.
Nilai Shapley yang tepat mempertimbangkan setiap kemungkinan susunan/subset ciri, yang berkembang secara eksponen dengan bilangan ciri.
TreeSHAP mengeksploitasi struktur pepohon keputusan untuk mengira nilai Shapley tepat dalam polinomial dan bukannya masa eksponen.
SHAP can help inspect a model’s predictions, but legal duties vary and attribution does not establish causality or fairness.
SHAP documentation describes summary plots as showing feature impact across instances; plotted SHAP values display the range and distribution of those effects.
