DATA EXTENSION DEVICE, LEARNING DEVICE, DATA EXTENSION METHOD, AND RECORDING MEDIUM

摘要

Provided is a data extension device, wherein a data acquisition means acquires, from a data group of a source domain, two pieces of source domain data of a prescribed class, and acquires, from a data group of a target domain, one piece of target domain data of a prescribed class. An estimation means estimates the structure of a manifold which shows a data distribution of the source domain by using the two pieces of source domain data. A data generation means generates new data of the target domain by using the one piece of target domain data and the structure of a manifold.
