| Summary: | In recent year, various models have been proposed for medical diagnosis, which broadly
can be classified into physical-based approaches and statistical-based approaches.
Uncertainty and imprecision are the most important problems in medical diagnosis,
other many problems in medical diagnostic domains need to be represented at varying
degrees of diagnosis to be solved. Moreover, classification is very important in
computer-aided medical diagnosis. In this respect, Artificial Neural Network (ANN)
have been successfully applied and with no doubt, they provide the ability and potentials
to diagnose the diseases. Therefore, this research focuses on using ANN to classify
medical data. ANN model with two layers of tunable weights were used and trained
using four different backpropagation algorithms while are the gradient descent(GD),
gradient descent with momentum(GDM), gradient descent with adaptive learning
rate(GDA) and gradient descent with momentum and adaptive learning rate(GDX). The
network was used to classify three sets of medical data taken from UCI machine
learning repository. The ability of all training algorithms tested and compared to each
other on all datasets. Simulation results proved the ability of ANN for medical data
classification with high accuracy and excellent performance and efficiency. This
research provides the possibility of reduce costs and human resources. Increasing speed
to find the results of medical analysis by using ANN also contributes in saving time for
both physicians and patients |
