Abstract
An input of a first observation signal corresponding to an incoming signal from a first direction is received, an angular rotation operation of the first observation signal is performed to obtain a second observation signal corresponding to an incoming signal from a second direction that is different from the first direction and the second observation signal is added to a set of training data.
Claims8
A training data augmentation device comprising processing circuitry configured to:
- receive an input of a first observation signal corresponding to an incoming signal from a first direction and performs an angular rotation operation of the first observation signal to obtain a second observation signal corresponding to an incoming signal from a second direction that is different from the first direction;
- and
- add the second observation signal to a set of training data.
A training data augmentation method comprising:
- an angular rotation operation step of receiving an input of a first observation signal corresponding to an incoming signal from a first direction and performing an angular rotation operation of the first observation signal to obtain a second observation signal corresponding to an incoming signal from a second direction that is different from the first direction;
- and
- a training data addition step of adding the second observation signal to a set of training data.
