Abstract
[Object] To provide a sound source separation technology capable of improving the separation performance. [Solution] An information processing apparatus including: an acquisition section configured to acquire an observation signal obtained by observing a sound; and a sound source separation section configured to separate the observation signal acquired by the acquisition section into a plurality of separated signals corresponding to a plurality of assumed sound sources by applying a non-linear function to a matrix product of an input vector and a coefficient vector corresponding to each of the plurality of sound sources.
Claims13
An information processing apparatus comprising:
- an acquisition section configured to acquire an observation signal obtained by observing a sound;
- and
- a sound source separation section configured to separate the observation signal acquired by the acquisition section into a plurality of separated signals corresponding to a plurality of assumed sound sources by applying a non-linear function to a matrix product of an input vector and a coefficient vector corresponding to each of the plurality of sound sources.
An information processing method which is executed by a processor, comprising:
- acquiring an observation signal obtained by observing a sound;
- and
- separating the acquired observation signal into a plurality of separated signals corresponding to a plurality of assumed sound sources by applying a non-linear function to a matrix product of an input vector and a coefficient vector corresponding to each of the plurality of sound sources.
A recording medium having a program recorded thereon, the program causing a computer to function as:
- an acquisition section configured to acquire an observation signal obtained by observing a sound;
- and
- a sound source separation section configured to separate the observation signal acquired by the acquisition section into a plurality of separated signals corresponding to a plurality of assumed sound sources by applying a non-linear function to a matrix product of an input vector and a coefficient vector corresponding to each of the plurality of sound sources.
