Abstract

The embodiment of the invention provides a training method of a product purchase probability prediction model and a purchase probability prediction method. The training method comprises the steps of obtaining user information of a training sample user, all historical purchase information, target purchase information in a preset time period and product information of the products corresponding to the historical purchase information; determining first associated feature information based on the historical purchase information and the target purchase information; determining second associated feature information based on the user information and the product information; and determining a training sample set according to the user information, the target purchase information, the first associated feature information, the second associated feature information and the product information, and performing model training according to the training sample set to obtain a purchase probability prediction model. According to the scheme, the accuracy of predicting the purchase probability through the trained prediction model is high, higher recommendation accuracy is achieved when products are recommended on the basis of the predicted purchase probability, and the purchase requirements of users can be better met.

Description

technical field [0001] The present application relates to the field of data processing, and in particular, the present application relates to a method for training a product purchase probability prediction model and a purchase probability prediction method. Background technique [0002] With the rapid development of the financial industry, various financial products emerge in an endless stream. In order to facilitate the purchase of financial products by users, it is necessary to recommend financial products to users. [0003] When recommending financial products in the prior art, the accuracy of product recommendation is low, and the financial products recommended for users may not meet the purchase needs of users, resulting in poor user experience. Contents of the invention [0004] The purpose of this application is to at least solve one of the above-mentioned technical defects. The technical scheme adopted in this application is as follows: [0005] In the first aspe...
