Abstract
A sound source separation program causes a computer to acquire an acoustic signal, convert the acquired acoustic signal from a time region to a frequency region, and perform sound source separation on the acoustic signal converted to the frequency region by performing updating based on elementary row operation on a demixing matrix to iteratively minimize an objective function including a quadratic form of a separation vector and a determinant of the demixing matrix.
