Application of clustering algorithms and classification methods for identifying stench data of automobiles

Abstract

There has been steady increase in consumer’s complaint about the affective quality for automobiles such as the stench inside an automobile. In order to improve the affective quality of smell for consumer, it is crucial to cluster or classify the types of smell at first. We apply several clustering algorithms, such as hierarchical algorithm and K-means algorithm, and classification models, such as decision tree and artificial neural network, and support vector machine, to 26 indices provided from ‘A’ automobile company. After determining optimal number of clusters, we apply three classification methods and compare their performance in terms of computational time and accuracy.
