Abstract

In building a classification model, variables containing low predictive information are sometimes used. This can increase the bias on classification. Weight of Evidence (WoE) and Information Value (IV) provide a good theoretical foundation to explore, filtering, and transforming variables in binary classification. The value of IV can help measure the predictive power possessed by a variable in separating binary classes. This research implements this framework to screen 24 predictor variables that will be used in the svm classification model to improve the evaluation of the food insecure household classification model. We use the National Socioeconomic Survey by the Indonesian Central Bureau of Statistics in 2020 for West Java Province and 2021 for East Java Province to produce a classification model. The results of this study showed that WOE was able to improve the model evaluation value from the AUC value of 0.81 to 0.83 for West Java Province and the AUC value of 0.58 to 0.66 for East Java Province.
