Collecting sufficient data without distribution bias is essential to improve the performance of artificial intelligence (AI) analysis. AI technology is required to collect data dispersed across multiple institutions and safely perform integrated analysis while keeping certain information confidential, such as personal information and know-how. Specifically, the use of data is believed to be restricted if personal information is involved and identifiable in the shared data.Collecting sufficient data without distribution bias is essential to improve the performance of artificial intelligence (AI) analysis.
