Title:
ELECTRONIC LETTER-OF-GUARANTEE VALUE PREDICTION METHOD AND APPARATUS BASED ON PRIVACY COMPUTING
Document Type and Number:
WIPO Patent Application WO/2024/066042
Kind Code:
A1
Abstract:
An electronic letter-of-guarantee value prediction method and apparatus based on privacy computing. The method comprises: constructing a machine learning model, and using a federated learning method to design, in the machine learning model, a feature variable template conforming to letter-of-guarantee value prediction (S101); each participant collecting data on the basis of the feature variable template of a local machine learning model, inputting the data into its own local machine learning model for training, and outputting a numerical vector of the degree of contribution of each participant to a letter-of-guarantee value (S102); a public machine learning model establishing a self-attention model for a contribution value vector generated by each participant, mapping all contribution values into a single vector, and dynamically calculating the weight of each participant (S103); and inputting the mapped single vector into the local machine learning model of each participant, and performing final letter-of-guarantee value prediction (S104). Therefore, a high-value reference can be provided for a guarantee company, such that the working efficiency of insurance personnel is improved.
