Abstract: This application provides a model training method and a related apparatus. In the method, a second communication apparatus receives a first neural network parameter of a first communication apparatus, and sends first indication information to the first communication apparatus when a correlation coefficient between the first neural network parameter and a second neural network parameter of the second communication apparatus is less than a first threshold. The first indication information indicates that the second communication apparatus is to participate in training of a first neural network model of the first communication apparatus. That the correlation coefficient between the first neural network parameter and the second neural network parameter is less than the first threshold indicates that the second neural network parameter makes a great contribution to convergence of the first neural network model.

Abstract: A data transmission method and apparatus are described. The method includes a receive end receiving a first parameter, where the first parameter includes a parameter of a probability distribution of a hidden variable. The hidden variable is obtained by encoding first data by using an encoder of a variational auto-encoder. The receive end determines the probability distribution based on the first parameter, and samples the probability distribution M times to obtain M pieces of sampled data, where M is a positive integer. The receive end reconstructs the first data based on the M pieces of sampled data. According to the described data transmission method and apparatus, the first parameter is transmitted, so that the receive end can support a plurality of times of sampling, thereby reducing an amount of data transmitted over an air interface, and reducing data transmission overhead.
