Prediction of Customer Churn in Banking Industry
This work addresses customer retention for banks, but it is incremental as it applies existing methods to a specific dataset.
The study compared six supervised classification techniques to predict customer churn in the banking industry using data from 10,000 European bank customers, finding that an artificial neural network (ANN) with five nodes in a single hidden layer performed best without overfitting issues.
With the growing competition in banking industry, banks are required to follow customer retention strategies while they are trying to increase their market share by acquiring new customers. This study compares the performance of six supervised classification techniques to suggest an efficient model to predict customer churn in banking industry, given 10 demographic and personal attributes from 10000 customers of European banks. The effect of feature selection, class imbalance, and outliers will be discussed for ANN and random forest as the two competing models. As shown, unlike random forest, ANN does not reveal any serious concern regarding overfitting and is also robust to noise. Therefore, ANN structure with five nodes in a single hidden layer is recognized as the best performing classifier.
