The a.cura.y of these techniques is grea.ly a.fected by cha.ging their pa.a.eters. Hyperpa.a.eter optimiza.ion pla.s a.crucia. role in improving model performa.ce. In this work, the Pa.ticle swa.m Optimiza.ion (PsO) a.gorithm wa. used to effectively sea.ch the hyperpa.a.eter spa.e a.d improve the predictive power of the ma.hine lea.ning models by identifying the optima. hyperpa.a.eters tha. ca. provide the highest a.cura.y. a.da.a.et with a.va.iety of clinica. a.d epidemiologica. cha.a.teristics linked to COVID-19 ca.es wa. used in this study.

To eva.ua.e the predictive performa.ce of the models, the a.cura.y metric wa. employed. The experimenta. findings showed tha. the suggested method of estima.ing COVID-19 risk is effective. When compa.ed to ba.eline models, the optimized ma.hine lea.ning models performed better a.d produced better results.
