Title:
DATA PREDICTION SYSTEM AND DATA PREDICTION METHOD
Document Type and Number:
Japanese Patent JP2019095912
Kind Code:
A
Abstract:
To provide a data prediction system that conducts predictions according to a plurality of learned prediction models, and changes an aggregate rule of a plurality of prediction values calculated based on these prediction models in accordance with a prediction environment condition by group decision making type determination means.SOLUTION: A data prediction system of the present invention comprises: a first storage unit storing data to be used in a prediction and a second storage unit storing a plurality of prediction models to be used in the prediction; a data acquisition unit; a model learning unit that adjusts a parameter about prediction accuracy of each of the plurality of prediction models, respectively; an inter-model relationship learning unit that generates a tallying rule, based on an inter-model relationship, for tallying each calculated prediction value data on the basis of a learning condition; a prediction processing unit that calculates prediction value data by a plurality of learned prediction models, respectively; a prediction result tally unit that tallies each calculated prediction value data; a data output unit; and a control unit.SELECTED DRAWING: Figure 3
