MODEL TRAINING METHOD, CONSTRUCTION SAFETY EVALUATION METHOD, APPARATUS, AND DEVICE

Abstract

A model training method includes: obtaining sample data; determining a tag missing ratio of the training sample in different dimensions and a first weight value of the training sample in different dimensions according to association information between a training sample and a true value tag; determining a second weight value of the training sample according to the tag missing ratio; and inputting the sample data, the first weight value, and the second weight value into a preset neural network model for training, until a loss value of a target loss function of the preset neural network model meets a model convergence condition to obtain a target prediction model.
