Title:
DATA PREDICTION SUPPORT METHOD AND DATA PREDICTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/014035
Kind Code:
A1
Abstract:
This system extracts a plurality of data set candidates from a plurality of pieces of observation data having periodicity. The data set candidate is a set of two or more pieces of observation data for a target period. The system calculates vector data for each data set candidate, the vector data including, as elements, the magnitudes of a plurality of different frequency components of the observation data for each piece of the observation data in the dataset candidate, the system classifies two or more pieces of the vector data into one or more data groups on the basis of a distance between pieces of the vector data, and the system calculates the goodness of fit to a prediction model with the observation data serving as the input and the prediction data serving as the output, on the basis of the number of data pieces for each data group. The system outputs a data set candidate to be used for prediction using the prediction model, on the basis of the goodness of fit that is calculated for each data set candidate.
