In this paper, we propose the application of machine learning (ML) techniques to predict surgical risks based on pre-operative data. We used three supervised learning algorithms: Logistic Regression (LR), Random Forest (RF), and Support Vector Machine (SVM). A stacked ensemble model combining these algorithms was also explored to enhance the prediction accuracy. The proposed ensemble model achieved a prediction accuracy of 94 Artificial Intelligence and Machine Learning Surgical Complications Machine Learning En-semble Learning Logistic Regression Random Forest Support Vector Machine Prediction Healthcare Full Text Additional Declarations The authors declare no competing interests.
