In machine learning, backpropagation is a gradient computation method commonly used for training a neural network in computing parameter updates. It is an efficient application of the chain rule to …

Oct 6, 2025 · Backpropagation, short for Backward Propagation of Errors, is a key algorithm used to train neural networks by minimizing the difference between predicted and actual outputs.

Backpropagation is a machine learning technique essential to the optimization of artificial neural networks. It facilitates the use of gradient descent algorithms to update network weights, which is …

This is the whole trick of backpropagation: rather than computing each layer’s gradients independently, observe that they share many of the same terms, so we might as well calculate each shared term …

Mar 31, 2024 · In this post, we discuss how backpropagation works, and explain it in detail for three simple examples. The first two examples will contain all the calculations, for the last one we will only …

Nov 3, 2017 · Here we tackle backpropagation, the core algorithm behind how neural networks learn. If you followed the last two lessons or if you’re jumping in with the appropriate background, you know …

Dec 16, 2025 · Master backpropagation from computational graphs to gradient flow. Learn the chain rule, implement forward/backward passes, and understand automatic differentiation.
