Optimization Learning Vector Quantization Using Genetic Algorithm for Detection of Diabetics
Authors: Permana Inggih , Rozanda Nesdi Evrilyan , Syafria Fadhilah , Salisah Febi Nur 
Published: January 2019

This study proposed the method to improve the result of Learning Vector Quantization (LVQ) by optimizing the weight vectors using a genetic algorithm (GA) to detect the diabetics. Initial value of individuals for GA is taken from weight vectors which come from the last m iterations of LVQ training result. The result of experiment showed that there is a significant increase in sensitivity level, however there is a significant decrease in specificity level. It means the proposed method success in improving the LVQ ability to recognized the diabetics, but it lowers the ability of LVQ to recognize the people unaffected by diabetes.<!--[if gte mso 9]><xml>
