摘要: Purpose – Churn prediction is a very important task for successful customer relationship management. In general, churn prediction can be achieved by many data mining techniques. However, during data mining, dimensionality reduction (or feature selection) and data reduction are the two important data preprocessing steps. In particular, the aims of feature selection and data reduction are to filter out irrelevant features and noisy data samples, respectively. The purpose of this paper, performing these data preprocessing tasks, is to make the mining algorithm produce good quality mining results. Design/methodology/approach – Based on a real telecom customer churn data set, seven different preprocessed data sets based on performing feature selection and data reduction by different priorities are used to train the artificial neural network as the churn prediction model. Findings – The results show that performing data reduction first by self-organizing maps and feature selection second by principal component analysis can allow the prediction model to provide the highest prediction accuracy. In addition, this priority allows the prediction model for more efficient learning since 66 and 62 percent of the original features and data samples are reduced, respectively. Originality/value – The contribution of this paper is to understand the better procedure of performing the two important data preprocessing steps for telecom churn prediction. 出版者: London: Emerald Group Publishing Limited 出版日期: 2014-01-01 出處: Kybernetes, 2014-01, Vol.43 (5), p.737-749 版權: Emerald Group Publishing Limited 版權: Copyright Emerald Group Publishing Limited 2014 識別號: ISSN: 0368-492X 識別號: EISSN: 1758-7883 識別號: DOI: 10.1108/K-03-2013-0045 識別號: CODEN: KBNTA3
