Attribute enumeration system, attribute enumeration method, and attribute enumeration program

摘要

The enumeration plan generation unit 81 generates a set of logical expression structures expressing how to combine logical expression expressing the combination of attributes from the learning data attribute and the maximum number of combinations of the attributes, and generates each logical A partial logical expression structure obtained by dividing the logical expression included in the expression structure into two parts is generated, and an enumeration plan associated with the logical expression structure of the division source is generated. The attribute generation unit 82 generates a new attribute obtained by combining the attributes according to the generated partial logical expression structure. In addition, the enumeration plan generation unit 81 divides the logical expression structure into two so that the number of attributes included in the two partial logical expression structures generated from the respective logical expression structures is equal.
