How does backpropagation work in deep learning?

The question is about deep learning

Answer

Backpropagation is a key algorithm in deep learning used to train neural networks by adjusting weights based on the error rate obtained from the output. It works by propagating the error backward through the network's layers, updating weights to minimize the loss function. This iterative process continues until the model achieves satisfactory performance. Backpropagation relies on the chain rule of calculus to compute gradients efficiently, enabling the network to learn from data. Despite its effectiveness, it requires careful tuning to avoid issues like vanishing gradients.
