Document Type and Number:

Japanese Patent JP5164209

Kind Code:

B2

Abstract:

To generate a high-accuracy classification model related to a target classification system by efficiently using not only data on the target classification system but also data on an auxiliary classification system.

This classification device 1 uses not only already classified data in the target classification system but also already classified data in the auxiliary classification system, estimates weight so as to minimize expected error as total of a product of an error function and the weight, generates the classification model by use of the estimated weight and two kinds of already classified data to effectively use not only the data of the target classification system but also the data of the auxiliary classification system, and can generate the high-accuracy classification model related to the target classification system.
