Abstract

The invention relates to the technical field of Fintech, in particular to a model generation method and device. The method is suitable for a network embedding model with objects as nodes and relations among the objects as edges. Each node comprises a feature vector representing an object attribute. The method comprises: a first server obtaining second sample data and a second feature vector of a second node; wherein the second feature vector is obtained after a second server uses the second sample data to train a second network embedded model; wherein the first network embedding model is determined according to first sample data without a label value; the first server using the second sample data to train the first network embedded model, and if a training termination condition is met, stopping training; otherwise, returning to the step of obtaining the second sample data and the second feature vector of the second node.

Description

technical field [0001] The present invention relates to the field of technology finance (Fintech), in particular to a method and device for generating a model. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field. The traditional financial industry is gradually transforming into financial technology (Finteh). Information recommendation technology is no exception. However, due to the security and real-time requirements of the financial industry, It also places higher demands on technology. [0003] Traditional information recommendation is mainly based on the location of the device and the context at the time to decide whether to make a recommendation, and this recommendation model usually needs to be trained and tuned by collecting historical data. In the actual information recommendation business, it is often necessary to expand from one city A to another city B. Here, A has past informatio...
