WebMar 9, 2024 · The back propagation neural network maps the input, output, and the errors nonlinearly to the PID controller’s three parameters, k p, k i, and k d. In addition, the BP neural network has three neuron points for the input layer, five for the buried layer, and three for the output layer. Backpropagation efficiently computes the gradient by avoiding duplicate calculations and not computing unnecessary intermediate values, by computing the gradient of each layer – specifically, the gradient of the weighted input of each layer, denoted by – from back to front. See more In machine learning, backpropagation is a widely used algorithm for training feedforward artificial neural networks or other parameterized networks with differentiable nodes. It is an efficient application of the See more 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 loss function that computes a scalar loss for the final output, backpropagation … See more Motivation The goal of any supervised learning algorithm is to find a function that best maps a set of … See more 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 … See more Backpropagation computes the gradient in weight space of a feedforward neural network, with respect to a loss function. Denote: • $${\displaystyle x}$$: input (vector of features) • $${\displaystyle y}$$: target output See more 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"). See more 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. Assuming one output neuron, the squared error function is See more
