DECISION TREE GENERATION PROGRAM, DECISION TREE GENERATION METHOD, AND DECISION TREE GENERATION APPARATUS

摘要

A decision tree is so generated as to match the structure of the decision tree defined by the restriction condition from a case set in which values for a plurality of attributes and conclusions are associated, while referring to a restriction condition DB storing the restriction condition defining the structure of the decision tree. Accordingly, for example, even if new cases are added to the case set, the restriction conditions allows succession of the basic structure of the decision tree, and a situation in which the operator is not required to significantly modify the decision tree can be avoided. Thus, modification of the decision tree by the operator can be reduced.
