Title: LEARNING-TYPE SIGNAL SEPARATION METHOD AND LEARNING-TYPE SIGNAL SEPARATION DEVICE
Abstract:
A learning-type signal separation method wherein a model formulation unit is used to carry out a learning process on the basis of a training signal that contains a specific component and a training signal that does not contain the specific component, said training signals including a common characteristic. In this learning-type signal separation method, the model formulation unit is made to carry out a learning process in which there is generated a signal of a data sequence obtained by separating and removing the specific component from the data sequence of the training signal on the basis of the training signal and information indicating whether the specific component is contained in the training signal, thereby generating learned data; an arbitrary signal containing the common characteristic is obtained; and there is generated a signal of a data sequence obtained by separating and removing the specific component from the data sequence of the acquired arbitrary signal on the basis of the arbitrary signal and the learned data that has been generated.
