Fig. 2.

Effect of different levels of SNR on inter-individual variations of CDE curves. a–c CDE of the multivariate Gaussian data with SNR = 10 dB, 5 dB, and 0 dB respectively. Here, the degree of inter-individual variation (DIIV) of community structure is 0 and the dataset is simulated without HRF. The number of communities is $K$ = 6 for all of the experiments in this figure and the black plot is the group-averaged CDE curve. d–f The extrema of the individual-level CDE curves with different levels of SNR. The red dots are the local maxima and the blue dots are the local minima of 100 virtual subjects. The black plot is the group-averaged CDE curve. g The time deviation of local maxima of individual-level CDE curves compared to the local maximum of the group-averaged CDE curve with different levels of SNR. h The time deviation of local minima of individual-level CDE curves compared to the local minimum of the group-averaged CDE curve with different levels of SNR.
