Comparison of the sensitivity of model fitness of BCPD-based states with that of block-based states using synthetic data. a Local fitting using the group-averaged adjacency matrix of BCPD-based discrete states (States 1 to 5 at time points $t$ = 44, 74, 98, 130, 154) with HRF and SNR =5 dB. b Local fitting using the group-averaged adjacency matrix of block-based states (States 1 to 5 at time points $t$ = 35, 65, 90, 115, 145) with HRF and SNR = 5 dB. c Local fitting using the group-averaged adjacency matrix of BCPD-based discrete states (States 1 to 5 at time points $t$ = 43, 75, 98, 125, 154) with HRF and SNR =10 dB. d Local fitting using the group-averaged adjacency matrix of block-based states (States 1 to 5 at time points $t$ = 35, 65, 90, 115, 145) with HRF and SNR = 10 dB. Different colors represent the PPDI values of different states with the true number of communities $K^{true}$. All experiments use the window $W_l$ = 20 for calculating the adjacency matrices.
