BSS results on MRS data. An example of the results of blind separation of two simulated MRS metabolites. The number of observations N is set to 32, and the SNR value is 10 dB. (a) Cho and Ins source metabolites. (b) Two of the observations. (c-h) Separated metabolites by ${\text{JD}}_{\text{LU}}^{+}$-ICA, ${\text{JD}}_{\text{QR}}^{+}$-ICA, CoM ₂, SOBI, NNICA, and NMF, respectively.
