Fig. 4: Observed subject EEG spectra, inferred SGM parameter posterior distributions, and corresponding simulated spectra.
From: Simulation-based inference of developmental EEG maturation with the spectral graph model
Posterior predictive checks, comparing simulation-based inference (SBI) of the spectral graph model (SGM) derived spectral realizations to observed data, are shown for three representative subject EEGs a, c, e. Observed EEG spectra are demonstrated in a, c, e (black traces), and their respective approximated SGM parameter posterior distributions obtained with SBI are shown in b, d, f. The mean values (red lines in b, d, f) of respective SGM parameter posterior distributions were used to simulate spectra with SGM and yielded simulated spectra (red-dashed traces) shown in a, c, e. The simulated spectra have characteristics similar to those of the observed data, including posterior dominant rhythm (PDR) center frequency and spectral slope.
