摘要

PPROBLEM TO BE SOLVED: To provide a multivariable decision tree construction system for shortening computational complexity and a calculation time for constructing a multivariable decision tree (MDT), and for easily understanding the decision content of the MDT. PSOLUTION: This multivariable decision tree construction system 1 is configured to construct a multivariable decision tree where multivariable test functions for dividing data are installed in every non-terminal end node by using a plurality of data for training equipped with element data. The multivariable decision tree construction system 1 is provided with a group label applying means 2 for applying the group label information showing groups into which the data should be divided in the non-terminal end nodes to data for training in every non-terminal end node. A multivariable test function generating means 2 corrects classification data, based on the group label information, and generates the multivariable test functions for every non-terminal node, based on the corrected classification data.
