client validity features, and combining the
client validity features and the derivative features into a
feature data set; constructing a
customer classification model according to the
feature data set, and adjusting and optimizing the
customer classification model to obtain an optimized customer classification model; performing key
feature screening on the
feature data set according to the optimized customer classification model to obtain key features; and performing customer classification on preset customer data according to the key features and the optimized customer classification model, and outputting a customer
classification result. By acquiring the multi-dimensional data and creating the derivative features, the depiction ability of the customer features is improved, and the accuracy of customer classification is improved.
