Title:
METHOD AND DEVICE FOR ADJUSTING MODEL PARAMETERS, AND STORAGE MEDIUM AND PROGRAM PRODUCT
Document Type and Number:
WIPO Patent Application WO/2022/156159
Kind Code:
A1
Abstract:
A method and device for adjusting model parameters, and a storage medium and a program product, which relate to the field of secure multi-party computing, such as multi-party machine learning, federated learning and joint modeling. The method comprises: classifying input data by using a classification model which is obtained by means of training based on secure multi-party computing, so as to obtain classification predicted values of the classification model (S201); reducing the classification predicted values (S202); normalizing the reduced classification predicted values, so as to obtain a normalization result of the classification predicted values (S203); and updating parameters of the classification model according to the normalization result of the classification predicted values (S204). Input values for a normalization method are reduced by reducing classification predicted values, such that data overflow can be avoided in a normalization process, and thus, the training precision of a classification model can be improved.
