WebIt is observed that resilient back propagation algorithm with log sigmoid activation function gives the lowest NMSE of 0.003745. The research work also uses Genetic Algorithm (GA) for weight optimization. BP suffers from the danger of getting stuck in local minima. This is avoided by using GA to select the best synaptic weights and node ... WebJul 13, 2024 · For the purpose of optimizing the weighting factors in cost functions of MPC, this article proposes an artificial neural network (ANN) based method, which applies genetic algorithm as the back propagation algorithm. Since this method is trained offline, it does not increase any computation complexity of MPC. just sports photography hershey bears
