We may be given a set of observations with the classes or clusters. The aim of this article is to provide an up-to-date review of different approaches to classification, compare their performance on a wide range of challenging data-sets. In this paper, machine learning algorithm classifiers based on CART, C4.5, CAL5, FACT, QUEST and statistical discriminant analysis are compared on various datasets in classification error rate and algorithms.

본 연구에서는 결정트리 분야에서 각 분류알고리즘을 살펴보고 통계학의 판별분석과 기계학습(Machine Learning)분야에서 분류알고리즘을 비교하고, 자료에 따라 오분류율을 분석 하였다.
