deep learning churn prediction

Customer churn is a big problem facing banks in the increasingly competitive market. By analyzing the reasons of bank customer churn, this paper puts forward a method of establishing customer churn prediction model. By using the model, we find out the forecast loss group, forecast the loss trend, and then formulate eff

For China's major telecom operators, in the overall market size is relatively stable, the maintenance of the existing customers is to ensure that the most important part of their profits. Therefore, the prediction of the possibility of customer churn is directly related to the operator's customer maintenance focus is correct or not. This article will be based on the "Bear" base case: Collect customer

Customer Churn "Loss rate" is a business term that describes the customer's departure or stop payment of a product or service rate. This is a key figure in many organizations, as it is usually more expensive to get new customers than to retain the existing costs (in some cases, 5 to 20 times times the cost). Therefore, it is invaluable to understand that it is valuable to maintain customer engagement because it is a reasonable basis for developing ret

The essence of deep learning is to learn more useful features by building machine learning models with many hidden layers and massive training data, which ultimately improves the accuracy of classification or prediction.

The very deep network structure has difficulty in the reverse propagation of the prediction error, because the prediction error is transmitted from the topmost layer to the bottom, the error to the bottom is very small, and it is difficult to drive the update of the underlying parameters.
