For example, AI is used in an application such as recognizing a person existing in an image captured by a monitoring camera. The learning model of AI is created by performing machine learning process using learning data before launching the AI. “The quality of learning model varies over time. This us because the data itself inputted to the learning model may vary over time, thereby outdating the learning model constructed when launching the AI. Therefore, in order to maintain and improve the operational quality of the system using the AI even after launching the system, it is important to monitor the quality of the learning model.
