Title:
RELATED APPARATUS OF MODEL TRAINING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/012219
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a model training method and a related apparatus, which are used for improving the generalization capability of prediction models. The method in the embodiments of the present application comprises: according to a first error of a prediction result of a prediction model on first sample data, a first output of an error imputation model and a probability of the first sample data being observed, calculating a loss function of the error imputation model; and according to the loss function of the error imputation model, updating parameters of the error imputation model, the first output of the error imputation model being used to represent a predicted value of the first error, the loss function of the error imputation model comprising a deviation term and a variance term, the deviation term being used for representing a deviation between an actual loss function and a theoretical loss function of the prediction model, and the variance term being used for representing a variance between the actual loss function and the theoretical loss function of the prediction model.
