WebBackpropagation involves the calculation of the gradient proceeding backwards through the feedforward network from the last layer through to the first. To calculate the gradient … 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… connecting to my linksys wireless router
