AI Insight
This study developed an intelligent system to predict stroke risk using eleven patient features and evaluated seven different machine learning algorithms. Ensemble methods (Random Forest, Stacking Classifier, and Bagging Classifier) achieved the highest accuracy at 99.52%, while Decision Tree models reached 98.24% accuracy. The research demonstrates that ensemble learning approaches significantly outperform traditional individual algorithms like logistic regression (77.03%) for stroke prediction tasks.
Why it matters
Early and accurate stroke prediction could enable timely preventive interventions, potentially reducing mortality rates and long-term disabilities associated with brain strokes. The high accuracy of ensemble methods suggests these AI-based diagnostic tools could support clinical decision-making and improve patient outcomes in healthcare settings.

Abstract: Brain stroke, known for its high mortality and incidence rates, poses significant health risks and requires rapid intervention for survival. Early diagnosis and preventive measures can greatly reduce life loss and disabilities. Recent advancements in deep learning have led to novel computer-aided diagnostic techniques for early stroke detection. This study proposes an intelligent system that predicts potential strokes using eleven features, evaluated through seven supervised machine learning algorithms. The process includes a literature review, dataset visualization, data preprocessing, and model evaluation. Ensemble methods like Random Forest, Stacking Classifier, and Bagging Classifier achieved high accuracies of 99.52%, while Decision Tree reached 98.24%. Other models, including KNN and TabNet, demonstrated reliable performance, achieving accuracies of 96.73% and 96.49%, respectively. The custom feedforward model achieved 94.91%, while SVC and logistic regression had lower accuracies at 88.06% and 77.03%. The results highlight the effectiveness of ensemble methods in stroke classification.
