Title:
PREDICTION SYSTEM AND METHOD
Document Type and Number:
Japanese Patent JP2019049850
Kind Code:
A
Abstract:
To provide a prediction system and a method capable of making an error of a predicted value as small as possible.SOLUTION: A prediction system: predicts a time transition of a prediction target in a prediction target period; calculates a reference value of the time transition of the prediction target; performs any one of filtering processing for removing outliers exceeding a predetermined range, filtering processing for removing a part of attribute information on an actual value, and filtering processing for obtaining coefficients for the attribute information used in a prediction value calculation with respect to at least one of a difference between a predicted time transition of the prediction target and the actual value of the time transition of the prediction target and a difference between a reference value of the predicted time transition of the prediction target and an actual value of the reference value; corrects the predicted time transition of the projection object and/or the reference value of the predicted time transition of the projection object by using a processing result of the filtering processing; and calculates a prediction result of the time transition of a final prediction object by using the corrected result.SELECTED DRAWING: Figure 3
