Title:
LEARNING DATA EXPANSION DEVICE, LEARNING DATA EXPANSION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/255318
Kind Code:
A1
Abstract:
In the present invention, a first observation signal corresponding to an arriving signal from a first direction is used as input and an angle rotation operation is performed with respect to the first observation signal, a second observation signal corresponding to an arriving signal from a second direction differing from the first direction is obtained, and the second observation signal is added to a set of learning data.
