“…response surface method (RSM) and artificial neural network (ANN) were compared regarding their modeling, sensitivity analysis and optimization abilities which concluded that the predictability of ANN model is better than RSM which emphasize the advantage of ANN in mapping the nonlinear behavior of the system. However, the ANN fitness function is integrated with particle swarm optimization (PSO) algorithm to optimize the output process parameters of the WEDM process [7]. B.…”
