Obesity Predictor Identification: Comparison of Correlation Based Feature Selection Method and Wrapper Method on Nutrition Dataset
The prevalence of obesity among Malaysians is estimated by calculating the obesity prevalence percentage using BMI prevalence data from the national health morbidity survey (NHMS). However, the nutrition data from the NHMS has not been used to predict the national obesity prevalence as it was collec...
