A Fuzzy Inference-Based Decision Support System for Disease Diagnosis

Abstract

Disease diagnosis is an exciting task due to many associated factors. Inaccuracy in the measurement of a patient’s symptoms and the medical expert’s expertise has some limitations capacity to articulate cause affects the diagnosis process when several connected variables contribute to uncertainty in the diagnosis process. In this case, a decision support system that can assist clinicians in developing a more accurate diagnosis has a lot of potentials. This work aims to deploy a fuzzy inference-based decision support system to diagnose various diseases. Our suggested method distinguishes new cases based on illness symptoms. Distinguishing symptomatic disorders becomes a time-consuming task in most cases. It is critical to design a system that can accurately track symptoms to identify diseases using a fuzzy inference system (FIS). Different coefficients were used to predict and compute the severity of the predicted diseases for each sign of disease. This study aims to differentiate and diagnose COVID-19, typhoid, malaria and pneumonia. The FIS approach was utilized in this study to determine the condition correlating with input symptoms. The FIS method demonstrates that afflictive illness can be diagnosed based on the symptoms. Our decision support system’s findings showed that FIS might be used to identify a variety of ailments. Doctors, patients, medical practitioners and other healthcare professionals could benefit from our suggested decision support system for better diagnosis and treatment.

“…CAD (Computer-Aided Detection/Diagnosis) systems are digital instruments which have emerged over the last 20 years to cope with problems related to the limits of human perception [13], aiming to analyze and process various types of medical images and produce an automatic or semi-automatic diagnosis [14]. These tools are often combined with AI (in particular with Machine Learning (ML)) in order to achieve the most reliable output possible [15].…”

Computer-aided diagnosis systems: a comparative study of classical machine learning versus deep learning-based approaches

“…In order to make the diagnostic task as objective as possible, different systems for analyzing and processing various types of medical images have been developed in recent years. These systems allow especially to characterize human tissues, suspicious regions, pathologies, etc., and to produce an automatic or semi-automatic diagnosis [ 1 ]. These are computer-aided diagnosis (CAD) systems.…”
