Model training method and apparatus, system, prediction method, and computer readable storage medium

A model training method, comprising:

• determining, by a first device, according to a description of data required for model training in a model training operation, a second device participating in model training, and sending a part of or the overall model training operation to the second device;
• and
• executing, by the first device, a first model training code in the model training operation to, for a jth training step, deliver by the first device a model parameter corresponding to the jth training step to the second device in response to the model training being not finished;
• and receiving a model parameter increment corresponding to the jth training step uploaded by the second device, and calculating a model parameter corresponding to a (j+1)th training step according to the model parameter increment corresponding to the jth training step uploaded by the second device;
• wherein determining whether the model training is finished comprises at least one of:
• in response to a difference between average loss function values corresponding to any two adjacent training steps from a (j+m+1) th training step to the jth training step being less than or equal to a preset threshold, determining that the model training is finished;
• or in response to a difference between average loss function values corresponding to at least two adjacent training steps from the (j+m+1) th training step to the jth training step being greater than the preset threshold, determining that the model training is not finished;
• wherein the first device is a centric training engine deployed on at an operation support system of a radio access network (RAN), and the second device is a distributed training engine deployed at a base station;
• or
• wherein the first device is a centric training engine deployed in an operation support system of a cable bearer network (BN), and the second device is a distributed training engine deployed in a Packet Transport Network (PTN) device.
