Title:
MODEL CONSTRUCTION SYSTEM AND MODEL CONSTRUCTION METHOD
Document Type and Number:
Japanese Patent JP2018170000
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a model construction system capable of alleviating an influence of sensitivity deterioration and judging whether or not a model is favorable.SOLUTION: Provided are: an NCLM processing part, a filter part, a model construction part, a variable narrowing part, a determination part, and a soundness calculation part. The NCLM processing part narrows a first input variable group including a plurality of input variables to a second input variable group selected by use of a NCLM. The filter part narrows the second input variable group to a third input variable group which satisfies predetermined condition. The model construction part constructs a model indicating relationship between the third input variable group and an output variable. The variable narrowing part narrows the first input variable group to the input variables not used for the model construction. The determination part determines whether or not a number of constructed models has reached a defined number. When the number of models has not reached the defined number, the first input variable group narrowed down by the variable narrowing part is outputted to the NCLM processing part, and the soundness calculation part calculates overall soundness of the defined number of models and the soundness of each of the models.SELECTED DRAWING: Figure 1
