Abstract:
Background: Since hospitalized patients with COVID-۱۹ are considered at high risk of death, the patients with the sever clinical condition should be identified. Despite the potential of machine learning (ML) techniques to predict the mortality of COVID-۱۹ patients, high-dimensional data is considered a challenge, which can be addressed by metaheuristic and nature-inspired algorithms, such as genetic algorithm (GA). Objective: This paper aimed to compare the efficiency of the GA with several ML techniques to predict COVID-۱۹ in-hospital mortality.Material and Methods: In this retrospective study, ۱۳۵۳ COVID-۱۹ in-hospital patients were examined from February ۹ to December ۲۰, ۲۰۲۰. The GA technique was applied to select the important features, then using selected features several ML algorithms such as K-nearest-neighbor (K-NN), Decision Tree (DT), Support Vector Machines (SVM), and Artificial Neural Network (ANN) were trained to design predictive models. Finally, some evaluation metrics were used for the comparison of developed models. Results: A total of ۱۰ features out of ۵۶ were selected, including length of stay (LOS), age, cough, respiratory intubation, dyspnea, cardiovascular diseases, leukocytosis, blood urea nitrogen (BUN), C-reactive protein, and pleural effusion by ۱۰-independent execution of GA. The GA-SVM had the best performance with the accuracy and specificity of ۹.۵۱۴۷e+۰۱ and ۹.۵۱۱۲e+۰۱, respectively. Conclusion: The hybrid ML models, especially the GA-SVM, can improve the treatment of COVID-۱۹ patients, predict severe disease and mortality, and optimize the utilization of health resources based on the improvement of input features and the adaption of the structure of the models.
