WebAbstract: This paper presents a way of combining BP (Back Propagation) neural network and an improved PSO (Particle Swarm Optimization) algorithm to predict the earthquake … WebOct 9, 2014 · The Back-Propagation Algorithm is recursive gradient algorithm used to optimize the parameters MLP wrt to defined loss function.Thus our aim is that each layer of MLP the hidden units are computed so that cost function is maximized. Like in logistic regression we compute the gradients of weights wrt to the cost function .
