Abstract

The invention discloses an enterprise information loss prediction method of a double-layer structure. The method comprises the steps: enabling a system to obtain a data set, and dividing the data setinto a training set and a test set; performing double-layer training on the training set by utilizing XGBoost, LightGBM, AdaBoost and a weighted voting algorithm, outputting evaluation indexes of a classification prediction model, and finally performing result analysis and comparison on the evaluation indexes of the classification prediction model and a comparison object. By using a double-layer fusion method and an adaptive algorithm, the accuracy and precision of the customer loss prediction model are improved, and the customer loss prediction model is further perfected.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a two-layer structure enterprise information loss prediction method. Background technique [0002] Today, various markets are becoming increasingly saturated and competitive, and the market share of industry giants is increasing. Entrepreneurs in various industries used to focus on launching novel customized services to attract new customers and convert existing customers. Convert into loyal customers. Studies have shown that the cost of developing a new customer is much higher than the cost of maintaining an old customer, so preventing the loss of old customers is a problem that entrepreneurs must pay attention to. [0003] Therefore, customer churn prediction technology is very important for enterprises to retain old customers and launch various customized services. For example, for a telecom company, if a lost customer no longer uses the service provided by the operator, he wi...
