Risk iAssessment of iDiabetes Type-II is crucial in ipreventing it and ireducing the risk of various comorbidities. There are many iexisting machine ilearning models for predicting iType-II diabetics in ishort term future or in unspecified future. But obtaining a model having optimal performance and predicting idiabetes risk in long term future are the main problems. iThese problems are ihandled in this work by iproposing ia stacking based integrated KELM imodel to predict the irisk of diabetes Type-II for a person within five years after assessment. The Pima Indian Diabetic Dataset (PIDD) and a Diabetic Research Center dataset are used in this study. iA Min-Max normalization is iused to pre-process ithe noisy idatasets. The HAFPSO ialgorithm used in ithis work iexplores the best combination of Base ilearners by increasing the iClassification Accuracy (CA) iand decreasingi the kernel icomplexity of the ioptimal learners. iFinally, the model is iintegrated by utilizing the iKELM as a meta-classifier that icombines the ipredictions of the twenty Base Learners. The iproposed imethod is assessed iwith different imeasures such as accuracy, isensitivity, ispecificity, Mathews iCorrelation iCoefficient, and Kappa Statistics. iThe proposed KELM-HAFPSO iapproach has got ibetter values iof the considered metrics confirming its effectiveness in identifying type-II diabetes. iThe proposed method helps the clinicians to predict the ipatients who iare at a ihigh risk of Type-II diabetes iin the ifuture with the ihighest iaccuracy of 98.5%. The results iobtained show that ithe KELM-HAFPSO iapproach is a ipromising new itool for identifying type-II diabetes.
