Illustrative fMRI dataset; here time course data were obtained on six subjects. The subject-specific connectivity between ten distinct regions of the brain was estimated using multiregression dynamical models applied (a) to each subject separately, (b) to all subjects jointly with regularity hyperparameter λ = 4. The graphs in (b) are 23% more similar compared to the graphs in (a), as explained in the main text. [Figure 1c provides a key.]
