Stroke is a global public health concern with severe consequences. Early detection and accurate prediction of stroke occurrence are crucial for effective prevention and targeted interventions. This study proposes a machine learning-based approach to predict the likelihood of stroke among patients. A dataset with demographic, clinical, and lifestyle factors is used, with models including logistic regression, decision trees, random forests, and support vector machines to build a risk prediction model.

Early detection and accurate prediction of stroke occurrence are crucial for effective prevention and targeted interventions. This study proposes a machine learning-based approach to predict the likelihood of stroke among patients. A comprehensive dataset encompassing demographic, clinical, and lifestyle factors of a large patient cohort was employed. Variables such as age, gender, hypertension, diabetes, smoking status, BMI, and medical history were considered. Advanced machine learning algorithms, including logistic regression, decision trees, random forests, and support vector machines, were utilized to analyses the dataset and develop a predictive model. The results demonstrate that the machine learning-based approach achieved high predictive accuracy in identifying individuals at risk of stroke. The model exhibited excellent sensitivity and specificity, enabling effective stratification of patients based on their stroke likelihood. Developing an accurate stroke prediction model using machine learning holds immense potential for proactive healthcare strategies and personalized patient care. Early identification of high-risk patients enables timely intervention and implementation of preventive measures, potentially reducing the burden of stroke-related complications. This study showed that the supervised K-Nearest Neighbors Algorithm (K-NN) model outperforms the other methods, with an accuracy of 95% compared with other models. Keywords Stroke prediction, Machine learning, Risk Predictive modelling, Healthcare interventions Introduction Stroke represents a significant global health challenge, accounting for a substantial proportion of morbidity and mortality worldwide. A stroke, also referred to as a brain attack, happens when a blood artery in the brain bursts or when blood flows to a certain area of the brain is restricted. Specific areas of the brain are damaged or lose function in both cases (National Heart, Lung, and Blood Institute, 2022) . According to the latest data published by the World Health Organization (WHO), stroke deaths in Malaysia alone reached 21,592 in 2020, accounting for approximately Submission: 7 October 2023; Acceptance: 2 November 2023 Copyright: © 2023.

These figures demonstrate the critical need for efficient stroke prevention measures and precise stroke risk prediction in patients. This emphasizes the significance of using more thorough and advanced techniques for stroke prediction. For instance, Dev et al.'s work from 2022 used machine learning and neural network to predict the occurrence of strokes among patients. With the help of a variety of factors age, heart disease, average glucose level, and hypertension, the researchers were able to identify those at risk of stroke with an astonishing 78% accuracy rate. This demonstrates how machine learning approaches can improve the estimation of the risk of stroke. The purpose of this study is to investigate how machine lea
