Web19 de mar. de 2024 · If you have read about Backpropagation, you would have seen how it is implemented in a simple Neural Network with Fully Connected layers. (Andrew Ng’s course on Coursera does a great job of explaining it). But, for the life of me, I couldn’t wrap my head around how Backpropagation works with Convolutional layers. For the basic case of a feedforward network, where nodes in each layer are connected only to nodes in the immediate next layer (without skipping any layers), and there is a loss function that computes a scalar loss for the final output, backpropagation can be understood simply by matrix multiplication. Essentially, backpropagation evaluates the expression for the derivative of the cost function as a product of derivatives between each layer from right to left – "backwards" – with th… dip with sour cream and ranch dressing
