Webbackpropagation algorithm: Backpropagation (backward propagation) is an important mathematical tool for improving the accuracy of predictions in data mining and machine learning . Essentially, backpropagation is an algorithm used to calculate derivatives quickly. WebApr 10, 2024 · Backpropagation is a popular algorithm used in training neural networks, which allows the network to learn from the input data and improve its performance over time. It is essentially a way to update the weights and biases of the network by propagating errors backwards from the output layer to the input layer.
