WebApr 10, 2024 · Let’s perform one iteration of the backpropagation algorithm to update the weights. We start with forward propagation of the inputs: The forward pass. The output of the network is 0.6718 while the true label is 1, hence we need to update the weights in order to increase the network’s output and make it closer to the label. WebJan 13, 2024 · In brief, backpropagation references the idea of using the difference between prediction and actual values to fit the hyperparameters of the method used. But, for applying it, previous forward proagation is always required.
