Document Type and Number:
WIPO Patent Application WO/2024/082514
Kind Code:
A1
Abstract:
Disclosed in the present application is a service index prediction method, comprising: determining an initiator data set of an initiator and a partner data set of a partner in vertical federated learning; encrypting the initiator data set by means of an initiator device, and sending the encrypted initiator data set to a partner device; decrypting a ciphertext correlation coefficient matrix by means of the initiator device, so as to determine a plaintext correlation coefficient matrix; determining an initiator correlation coefficient matrix and a partner correlation coefficient matrix according to the initiator data set and the partner data set; performing feature multi-collinearity analysis on the initiator and the partner according to the initiator correlation coefficient matrix, the partner correlation coefficient matrix and the plaintext correlation coefficient matrix; and determining model training data from the initiator data set and the partner data set according to the analysis result, and training a federated learning model by using the model training data. The training efficiency of a federated learning model is increased, and the feature interpretability of a linear model is ensured.
