Cluster partitioning evaluation device, cluster partition evaluation method and cluster division evaluation program

摘要

Problem to be solved: to divide the multidimensional space of the variable so that a plurality of prediction models having high accuracy can be used in accordance with the characteristics of the data.Cluster division evaluation apparatus of the present inventionInvestigation value of attribute of trading subjectAndA survey value acquisition department which acquires investigation value of economic force of a trading subjectIndicates the survey value of the attribute of the trading subject and the survey value of the economic force of the trading subjectA clustering unit divided into multiple clusters in multidimensional spaceUse the survey valueThe parameter of the forecasting model is assumed to be an object variable with the attribute of the trading subject as an explanatory variable, and the economic force of the trading subject is assumed as the target variable.Optimize for multiple clusters andThe predicted value of the economic force of the trading agent output by the optimization model isThe difference from the survey value of the economic power of the trading subjectEvaluate the number of clusters perBased on the results of the evaluationA regression analysis department that determines the number of clusters andIs provided.Diagram
