Intelligent card recommendation method and device based on neural network

The invention discloses an intelligent card recommendation method and device based on a neural network, and the method comprises the steps: obtaining a card recommendation request of a user, extracting the user features of the user according to the card recommendation request of the user, inputting the user features of the user into an intelligent card recommendation model, and obtaining the recommendation score of each card, wherein the intelligent card recommendation model is obtained by training and learning a training set consisting of historical data of each user, platform data of each terminal manufacturer, platform data of each issuing bank and platform data of a card organization, and recommending cards of which recommendation scores are greater than a preset threshold value to theusers. When the smart card recommendation model is trained, the used data sources are many, and the data dimension is wide, so that the recommendation success rate of the smart card recommendation model is high, and the card
