Backpropagation forms an important part of a number of supervised learning algorithms …
WebApr 23, 2024 · The aim of backpropagation (backward pass) is to distribute the total error back to the network so as to update the weights in order to minimize the cost function (loss). WebOct 31, 2024 · Backpropagation is a process involved in training a neural network. It involves taking the error rate of a forward propagation and feeding this loss backward through the …
WebJan 2, 2024 · Backpropagation uses the chain rule to calculate the gradient of the cost function. The chain rule involves taking the derivative. This involves calculating the partial derivative of each parameter. These derivatives are calculated by differentiating one weight and treating the other(s) as a constant. As a result of doing this, we will have a ... http://cs231n.stanford.edu/slides/2024/cs231n_2024_ds02.pdf
