Federal learning method for infectious disease probability prediction model, and device and related equipment

Abstract

The invention discloses a federated learning method for an infectious disease probability prediction model, and a device thereof and related equipment, which are applied to the technical field of artificial intelligence and are used for solving the technical problems of isolated island of training samples and poor confidentiality of user sample data of the infectious disease probability prediction model. The method provided by the invention comprises the following steps: obtaining user characteristics of a home terminal according to user data of the current mobile terminal, training and encrypting according to a previous gradient loss table obtained from a central server to obtain an encryption gradient and loss of the current mobile terminal, receiving a previous gradient loss table sent by a previous mobile terminal, when the first gradient loss table does not comprise the mask area, sending the first gradient loss table to a central server, newly building a gradient loss table and updating, when the first gradient loss table comprises the mask area, updating the first gradient loss table, and judging, training and updating the first gradient loss table in the later mobile terminal circularly until the loss function of the infectious disease probability prediction model converges.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, and in particular to a federated learning method, device, equipment and storage medium for an infectious disease probability prediction model. Background technique [0002] Since the beginning of winter, the new crown virus has now spread sporadically in various cities in China. Whether it is people at home or people who go to work every day, they can't feel at ease. As the holidays are approaching, people need to be subject to various restrictions when they want to go home and reunite. [0003] The current health management method for people is based on the itinerary code provided by the user on the one hand, and on the other hand, it requires people to take the initiative to perform nucleic acid testing. The location point is eliminated, and the users who have been to the location point are checked one by one. [0004] The defect of this management method is that: on th...
