This project presents the performance analysis of Particle swarm
optimization (PSO), hybrid PSO and Bayesian classifier to calculate the
epileptic risk level from electroencephalogram (EEG) inputs. PSO is an
optimization technique which is initialized with a population of random
solutions and searches for optima by updating generations. PSO is
initialized with a group of random particles (solutions) and then
searches for optima by updating generations. Hybrid PSO differs from
ordinary PSO by calculating inertia weight to avoid the local minima
problem. Bayesian classifier works on the principle of Bayes' rule in
which it is the probability based theorem. The results of PSO, hybrid
PSO and Bayesian classifier are calculated and their performance is
analyzed using performance index, quality value, cost function and
classification rate in calculating the epileptic risk level from EEG.
