Patent Searching and Data


Title:
A SOURCE SEPARATION DEVICE, A METHOD FOR A SOURCE SEPARATION DEVICE, AND A NON-TRANSITORY COMPUTER READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/084787
Kind Code:
A1
Abstract:
A purpose of the present disclosure is to provide a source separation method, a non-transitory computer readable medium, and a source separation apparatus. The source separation apparatus (100) includes an input means (101) for inputting mixture data obtained by mixing a plurality of data; and a matrix decomposition means (102) for separating the input mixture data by estimating a mixing/unmixing matrix (1021), a basis matrix for each source (10221), an activations matrix for each source (10222) and a reliability vector for each source (10223), and a means for unmixing of input mixture data (103) using the estimated matrices from the matrix decomposition means to estimate the sources.
