Application of Certainty Factor Method to Diagnose Venereal Diseases Using Confusion Matrix for Multi-Class Classification

Abstract

Public awareness about health is still deficient due to limited public knowledge in the health sector. Another problem is the limited availability of experts, especially in sexual health. Currently, health clinics that provide consultation for patients with venereal disease are still very limited. Awareness of venereal disease in Indonesia is still lacking, and there is still a reluctance to seek treatment or consult with venereal disease. Sexually transmitted diseases can be transmitted through sexual and non-sexual intercourse. Based on these problems, this study aims to build an expert system for diagnosing venereal diseases using the Certainty Factor method with Confusion Matrix for Multi-Class - Classification. The results of the study based on the accuracy test with the Confusion Matrix for Multi-Class Classification approach of 95% with an RMSE level of 0.091897
