Title:
データ分析方法、データ分析プログラム及びデータ分析装置
Document Type and Number:
Japanese Patent JP4300155
Kind Code:
B2
Abstract:
To simply compute a difference between data sets.
A plurality of decision trees, which estimate the values of explained variables from the values of explaining variables, are inputted, and the conditions of explaining variables under which each decision tree outputs the values of explained variables different to each other are computed as the different output conditions, or the conditions of explaining variables under which each decision tree outputs the values of the same explained variables are computed as the same output conditions, and then the different output conditions or the same output conditions thus computed are outputted.
