Parameter estimation in a whole-brain network model of epilepsy: Comparison of parallel global optimization solvers
Fig 2
Best solutions obtained by SaCeSS using 12 processors for the deterministic VEP model with weak coupling at source and sensor levels (problems 1 and 2).
(A) The simulated fast activities across brain regions at source level used for optimization. No propagation is observed due to weak coupling. (B) The true and estimated trajectories at phase-plane for three node types as Epileptogenic Zone (EZ, in red), Propagation Zone (PZ, in yellow), and Healthy Zone (HZ, in green). (C) The envelope of the simulated SEEG signals at the sensor level. (D) The confusion matrix indicates 100% accuracy in the estimation of three node types (EZ/PZ/HZ) based on SEEG signals.
