Abstract
The server device receives a model information from a plurality of terminal devices, and generates an integrated model by integrating the model information received from the plurality of terminal devices. The server device generates an updated model by learning a model defined by the model information received from the terminal device of update-target using the integrated model. Then, the server device transmits the model information of the updated model to the terminal device. Thereafter, the terminal device executes recognition processing using updated model.

A recognition system comprising:
- a plurality of terminal devices;
- and
- a server device,
- wherein at least one of the plurality of terminal devices includes:
- a terminal-side transmitter configured to transmit a model information defining a model used in a recognition processing to the server device;
