Hepatitis Disease Diagnosis Using Hybrid Case Based Reasoning and Particle Swarm Optimization

Abstract EN

Correct diagnosis of a disease is one of the most important problems in medicine.

Hepatitis disease is one of the most dangerous diseases that affect millions of people every year and take man’s life.

In this paper, the combination of two methods of PSO and CBR (case-based reasoning) has been used to diagnose hepatitis disease.

First, a case-based reasoning method is workable to preprocess the data set therefore a weight vector for every one feature is extracted.

A particle swarm optimization model is then practical to assemble a decision-making system based on the selected features and diseases recognized.

Many researchers have tried to have a more accurate diagnosis of the disease through the use of various methods.

The data used has been taken from the site UCI called hepatitis disease.

This database has 155 records and 19 fields.

This method was compared with five other classification methods and given the results of the proposed method (CBR-PSO), better results were achieved.

The proposed method could diagnose hepatitis disease with the accuracy of 93.25%.
