Integration of Explainable AI (XAI), specifically SHAP, allowed for clear identification of key risk factors such as blood glucose level, age, and work type. This enhances trust and provides actionable insights for medical professionals.
XAI in Action: Understanding Stroke Risk
SHAP analysis revealed that average blood glucose level and age are the most significant predictors of stroke risk. A positive SHAP value indicates an increased risk, while a negative value suggests a decreased risk. This granular insight helps clinicians personalize prevention strategies.
For example, a patient with higher glucose levels and older age would have a significantly elevated predicted risk, clearly explained by the model's feature contributions. This transparency builds trust and facilitates informed decision-making.
