Abstract

The invention discloses a bank customer data processing method and device. The method comprises the following steps: obtaining bank customer data which comprises one or any combination of personal data, transaction data and behavior data; and classifying the bank customer data according to the bank customer data and a pre-established classification model, wherein the classification model is pre-established according to a plurality of trained machine learning models, the plurality of trained machine learning models are selected from a machine learning model set by using a genetic algorithm, each trained machine learning model in the machine learning model set is provided with different hyper-parameters, and each machine learning model is trained according to historical data of bank customers. According to the invention, bank customer data can be processed conveniently, and high-accuracy and high-reliability customer data classification is realized.

Description

technical field [0001] The invention relates to the technical field of data analysis, in particular to a bank customer data processing method and device. Background technique [0002] Commercial banks have a large number of customers, and different customers have huge differences in consumption habits, consumption behaviors, and consumption capabilities. In order to provide each customer with more targeted and personalized services, commercial banks need to conduct customer analysis based on customer behavior, value and other data. Classification and refined management. [0003] With the increase in the number of commercial bank customers, customer consumption behavior is extremely complex, and the amount of data is increasing over time. The existing clustering algorithm or manual classification method can no longer meet the requirements of commercial banking for customer data classification results. , there is a problem of poor classification accuracy and reliability.
