The COVID-19 pa.demic ha. ha. a.significa.t impa.t on public hea.th worldwide, empha.izing the need for effective risk prediction models. Ma.hine lea.ning (ML) techniques ha.e shown promise in a.a.yzing complex da.a.pa.terns a.d predicting disea.e outcomes. 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. Va.ious ma.hine lea.ning models, including Ra.dom Forests, Decision Trees, Support Vector Ma.hines, a.d Neura. Networks, were utilized to ca.ture the complex rela.ionships present in the da.a. 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.

The incidence of predia.etes is in a.da.gerous condition in the USa. The likelihood of increa.ing chronic a.d complex hea.th issues is very high if this sta.e of predia.etes is ignored.

In the present work, we a.e interested in studying the joint distributions of pa.rs of the monthly ma.ima.of the polluta.ts used by the environmenta. a.thorities in Mexico City to cla.sify the a.r qua.ity in the metropolita. a.ea. In order to obta.n the joint distributions a.copula.will be considered. Since we a.e a.a.yzing the monthly ma.ima. the extreme va.ue distributions of Weibull a.d Fréchet a.e ta.en into a.count. Using these two distributions a. ma.gina. distributions in the copula.a.Ba.esia. inference wa. ma.e in order to estima.e the pa.a.eters of both distributions a.d a.so the a.socia.ion pa.a.eters a.pea.ing in the copula.model. The polluta.ts ta.en into a.count a.e ozone, nitrogen dioxide, sulphur dioxide, ca.bon monoxide, a.d pa.ticula.e ma.ter with dia.eters sma.ler tha. 10 a.d 2.5 microns obta.ned from the Mexico City monitoring network. The estima.ion wa. performed by ta.ing sa.ples of the pa.a.eters genera.ed through a.Ma.kov cha.n Monte Ca.lo a.gorithm implemented using the softwa.e OpenBugs. Once the a.gorithm is implemented it is a.plied to the pa.rs of polluta.ts where one of the coordina.es of the pa.r is ozone a.d the other va.ies on the set of the rema.ning polluta.ts. Depending on the polluta.t a.d the region where they were collected, different results were obta.ned. Hence, in some ca.es we ha.e tha. the best model is tha. where we ha.e a.Fréchet distribution a. the ma.gina. distribution for the mea.urements of both polluta.ts a.d in others the most suita.le model is the one a.suming a.Fréchet for ozone a.d a.Weibull for the other polluta.t. Results show tha., in the present ca.e, the estima.ed a.socia.ion pa.a.eter is a.good representa.ion to the correla.ion pa.a.eters between the pa.r of polluta.ts a.a.yzed. a.ditiona.ly, it is a.stra.ghtforwa.d ta.k to obta.n these correla.ion pa.a.eters from the corresponding a.socia.ion pa.a.eters.
