Model training system, operating method of model training system and portable electronic device

A model training system, comprising:

• a first model;
• at least one second model;
• an inputting unit used for providing an inputting data;
• and
• a processor used for executing an instruction set, wherein the instruction set includes:
• a difference analyzing unit used for obtaining a first intermediate layer data of the first model and a second intermediate layer data of the second model according to the inputting data, wherein a difference between the first intermediate layer data and the second intermediate layer data is a model difference between the first model and the second model;
• an accuracy analyzing unit used for inputting the inputting data to the second model to obtain an output value, and comparing the outputting value and a target value to obtain an outputting accuracy of the second model;
• and
• a model modifying unit used for updating at least one parameter of the second model according to the outputting accuracy and the model difference.

A portable electronic device, communicated with a server, wherein the server includes a first model, and the portable electronic device comprises:

• an inputting unit used for receiving an inputting data;
• a second model;
• and
• a processor used for executing an instruction set, wherein the instruction set includes:
• a difference analyzing unit used for obtaining a first intermediate layer data of the first model and a second intermediate layer data of the second model according to the inputting data, wherein a difference between the first intermediate layer data and the second intermediate layer data is a model difference between the first model and the second model;
• an accuracy analyzing unit used for inputting the inputting data to the second model to obtain an output value, and comparing the outputting value and a target value to obtain an outputting accuracy of the second model;
• and
• a model modifying unit used for updating at least one parameter of the second model according to the outputting accuracy and the model difference.
