It is an efficient application of the Zobacz więcej For more general graphs, and other advanced variations, backpropagation can be understood in terms of automatic differentiation, where backpropagation is a special case of reverse accumulation (or "reverse mode"). Zobacz więcej The gradient descent method involves calculating the derivative of the loss function with respect to the weights of the network. This is normally done using backpropagation. … Zobacz więcej • Gradient descent with backpropagation is not guaranteed to find the global minimum of the error function, but only a local minimum; also, … Zobacz więcej For the basic case of a feedforward network, where nodes in each layer are connected only to nodes in the immediate next layer (without skipping any layers), and there is a … Zobacz więcej Motivation The goal of any supervised learning algorithm is to find a function that best maps a set of inputs to their correct output. The motivation … Zobacz więcej Using a Hessian matrix of second-order derivatives of the error function, the Levenberg-Marquardt algorithm often converges faster than first-order gradient descent, especially when the topology of the error function is complicated.
