Machine learning approach using electrochemical immunosensor data for precise classification of Opisthorchis viverrini infection
Abstract
Opisthorchiasis, a major foodborne parasitic zoonotic disease in Thailand and neighboring countries, is caused by the carcinogenic liver fluke Opisthorchis viverrini (OV). Accurate classification of OV infection is critical for timely intervention and public health management. In this study, we propose a reliable machine learning (ML) classification model based on peak current data from an electrochemical immunosensor and additional patient condition features, which can facilitate intuitive decision-making without the need for expert personnel. This is the first report to classify OV infection using a ML algorithm integrated with electrochemical biosensor data. A total of 531 urine samples from both OV-positive and OV-negative individuals in endemic areas were analyzed using the immunosensor. We evaluated the effectiveness of six different ML models through cross-validation. Among these models, the decision tree and AdaBoost classifiers demonstrated outstanding performance, each achieving the highest accuracy of 90.65% (95% CI 0.89-0.91). The decision tree model yielded an F1 score of 91%, sensitivity of 95%, and specificity of 83%, while the AdaBoost model achieved an F1 score of 90%, sensitivity of 94%, and a higher specificity of 86%. The neural network model also performed excellently, with an accuracy of 89.72% (95% CI 0.84-0.93), and an F1 score of 89%. The statistical comparison of the model's performance highlighted the significant difference between the…
