Abstract

A machine learning apparatusis an apparatus for constructing, by transfer learning, a second identification dictionary to be used in a second task from a first identification dictionary to be used in a first task. The machine learning apparatusincludes: a pseudo data generation unitthat generates pseudo data by processing one of real data in the first task and real data in the second task or both pieces of real data; and a learning unitthat constructs a third identification dictionary by performing, using the first identification dictionary, first transfer learning using the pseudo data as training data, and furthermore, constructs the second identification dictionary by performing, using the third identification dictionary, second transfer learning using the real data in the second task as training data.
