Embodiment Construction

[0017] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the present invention will be further described in detail in the order of the basic principle, macro flow and specific steps in combination with the basic theory and formula drawings below.

[0018] Step 1. Preprocess the sample set.

[0019] There are many methods of data preprocessing: data cleaning, data integration, data transformation, data reduction, etc.

[0020] Data cleaning cleans data by filling in missing values, smoothing noisy data, identifying or removing outliers, and resolving inconsistencies. Realize format standardization, abnormal data removal, error correction, and duplicate data removal. Data integration combines data from multiple data sources and stores them in a unified manner to establish a data warehouse or data mart. Data transformation converts data into a form suitable for data mining through smooth aggregation, data general...

Abstract

The invention provides construction of a loss prediction model combining an echo state network and a support vector machine. Aiming at a non-ideal single model prediction effect, a classifier construction method is explored and improved, and the construction of the classifier can be divided into three aspects of a training set construction strategy, a classifier selection strategy and a predictionvalue determination strategy, comprehensively evaluating features and categories by fusing the Mahalanobis distance and the maximum information coefficient, and jointly measuring the redundancy between the features and the correlation degree between the features and the categories. The advantages of an echo state network and a support vector machine are integrated, and the problem of secondary optimization is solved through linear constraint, so that the performance of a telecom customer loss system is improved, and the prediction effect of a customer loss prediction model is improved.

Description

technical field [0001] The invention relates to the field of telecommunication customer churn classification, in particular to a customer churn prediction model based on a combined classifier. Background technique [0002] Under the current telecommunication market environment, attracting new customers and retaining existing customers have become two important themes of the customer management system of telecommunication operators. Predictive analysis of potential lost customers is a key link in the implementation of customer retention strategies, and has become a hot topic that is widely concerned in the academic and business circles. The purpose of customer churn prediction analysis is to predict customers with a high churn rate and correctly lock potential churn customer groups. On this basis, allocate and adjust limited marketing resources, formulate targeted customer retention strategies, improve the effectiveness of customer retention strategies, increase the return o...
