Joint modeling method, device and equipment and computer readable storage medium

Abstract

The invention discloses a joint modeling method and device, equipment and a storage medium, and the method comprises the steps: initializing model parameters, and transmitting the initialized model parameters to all data nodes; obtaining random loss gradient values in the neutral coordinator, dividing the random loss gradient values into first loss gradient values with the same number as the totalnumber of the data nodes, and distributing the first loss gradient values to the data nodes; acquiring a second loss gradient value of each data node based on the model parameter and the first loss gradient value; transmitting each second loss gradient value to a neutral coordinator, and determining a real loss gradient value of the data node according to each second loss gradient value and the random loss gradient value; updating model parameters based on the real loss gradient value to construct a model, and judging whether the model converges or not; and if the model converges, the model is constructed. According to the method and the system, the effect of predicting different types of data answers while information sharing is performed on multiple companies and privacy data is not leaked is achieved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a joint modeling method, device, equipment and computer-readable storage medium. Background technique [0002] Internet finance has developed rapidly in the past few years, and various financial technology companies are presenting a situation where a hundred schools of thought are contending and a hundred flowers are blooming. With the vigorous development of the industry, companies need to understand more and more data resources. Master all the data required for risk control, so the problem of information sharing will follow, but because many companies can easily cause some of their own private information to leak when sharing information, so although there will be many companies that have the joint model The needs of the company are often modeled alone, and have not been jointly modeled with other companies. And although the joint modeling technology has been mention...
