Publication number: 20240146580Abstract: An estimation system generates, from a value of a time series of an estimation object in a past period, a plurality of patterns of a transition of a value of the estimation object. Based on the plurality of generated patterns and a value of a time series of a factor in the past period, the estimation system specifies a dependency relationship between a transition pattern and a value of the factor and a transition pattern at a past (or future) time point and identifies a model in accordance with the specified dependency relationship. By inputting a value of a time series of the factor in a future period to the estimation model, the estimation system specifies a time series of a value in the future period of the estimation object using at least one transition pattern.Type: ApplicationFiled: March 8, 2022Publication date: May 2, 2024Inventors: Masato UTSUMI, Tohru WATANABE, Kazuki NAMBA, Ikuo SHIGEMORI, Hiroshi IIMURA, Hiroaki OGAWA, Daisuke HAMABA, Jun YAMAZAKI
