DIAGNÓSTICO DE DIABETES TIPO II POR CODIFICAÇÃO EFICIENTE E MÁQUINAS DE VETOR DE SUPORTE

Abstract

Diabetes is a disease caused by the pancreas failing to produce insulin. It is incurable and its treatment is based on a diet, exercise and drugs. The costs for diagnosis and human resources for it have become high and ine±cient. Computer- aided design (CAD) systems are essential to solve this problem. Our study proposes a CAD system based on the one-class support vector machine (SVM) method and the eficient coding with independent component analysis (ICA) to classify a patient's data set in diabetics or non-diabetics. First, the classification tests were done using both non-invasive and invasive characteristics of the disease. Then, we made one test without the invasive characteristics: plasma glucose concentration and 2-Hour serum insulin (mu U/ml), which use blood samples. We have obtained an accuracy of 99.84% and 99.28%, respectively. Other tests were made without the invasive characteristics, also excluding one non-invasive characteristic at a time, to observe the influence of each one in the final results.
