Title:
PREDICTION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/049546
Kind Code:
A1
Abstract:
The present invention: predicts a prediction target time trend for a prediction target period, and calculates a reference value for the prediction target time trend; for the difference between the predicted prediction target time trend and the actual value of the prediction target time trend and/or the difference between the reference value of the predicted prediction target time trend and the actual value of the reference value, executes a filtering process for eliminating an outlier value that exceeds a prescribed range, a filtering process for eliminating a portion of actual value attribute information, or a filtering process for deriving a coefficient with respect to the attribute information used in prediction value calculation; uses the processing results of the filtering process to correct the predicted prediction target time trend and/or the reference value of the predicted prediction target time trend; and uses the correction results to calculate a final prediction result for the prediction target time trend.
