Performance Analysis of Feature Selection Methods for Classification of Healthcare Datasets (original) (raw)

2019

Abstract

Classification analysis is widely used in enhancing the quality of healthcare applications by analysing data and discovering hidden patterns and relationships between the features, which can be used to support medical diagnostic decisions and improving the quality of patient care. Usually, a healthcare dataset may contain irrelevant, redundant, and noisy features; applying classification algorithms to such type of data may produce a less accurate and a less understandable results. Therefore, selection of optimal features has a significant influence on enhancing the accuracy of classification systems. Feature selection method is an effective data pre-processing technique in data mining, which can be used to identify a minimum set of features. This type of technique has immediate effects on speeding up classification algorithms and improving performance such as predictive accuracy. This paper, aims to evaluate the performance of five different classification methods including: C5.0, R...
