| Abstract(in English) | As in all service fields, the AI-based operation automation is progressing in the communication field as well. Once the AI model is built, it is not the end, and it is necessary to update the model according to changes in the external environment. Therefore, it is necessary to properly determine the update timing of the AI model, and for that purpose, a change detection technology is important. In this paper, we focus on time-series data that shows periodic fluctuations often observed in the communication field, propose a new change detection technology that solves the problems of existing technologies, and show the effectiveness of the proposed technology using both artificial and actual data. |
