Disease Prediction using Machine Learning Algorithms

Abstract

The development and exploitation of several prominent Data mining techniques in numerous real-world 
application areas (e.g. Industry, Healthcare and Bio science) has led to the utilization of such techniques in 
machine learning environments, in order to extract useful pieces of information of the specified data in healthcare 
communities, biomedical fields etc. The accurate analysis of medical database benefits in early disease prediction, 
patient care and community services. The techniques of machine learning have been successfully employed in 
assorted applications including Disease prediction. The aim of developing classifier system using machine 
learning algorithms is to immensely help to solve the health-related issues by assisting the physicians to predict 
and diagnose diseases at an early stage. A Sample data of 4920 patients’ records diagnosed with 41 diseases was 
selected for analysis. A dependent variable was composed of 41 diseases. 95 of 132 independent 
variables(symptoms) closely related to diseases were selected and optimized. This research work carried out 
demonstrates the disease prediction system developed using Machine learning algorithms such as Decision Tree 
classifier, Random Forest classifier, and Naïve Bayes classifier. The paper presents the comparative study of the 
results of the above algorithms used.
