More Information
Summary:The invention provides an Internet financial service information pushing method and system based on a user portrait, and the method comprises the steps: building a self-attention model and a user portrait classification model through obtaining template user behavior data containing different Internet financial service preferences and user portrait annotation data corresponding to the template user behavior data; and performing parameter optimization on the model by taking a feature distance of an interest embedding vector of template user behavior data of different Internet financial service preferences of the same service preference by expanding a user interest embedding unit as a training direction, so that user behavior features of different service preferences can be better captured and distinguished. Therefore, the accuracy and the individuation degree of pushing are improved. Besides, the image self-attention model and the user portrait classification model which meet the training convergence requiremen
