Forward propagation

WebForward propagation pertains to the image propagation in the CNN from the input layer to the output layer [322]. Let define the th image group at layer , and let describe the number of such groups. The image is determined by applying a pointwise sigmoid nonlinearity to an intermediate image , that is, (10.2) WebForward propagation: This is a technique used to find the actual output of neural networks. In this step, the input is fed to the network in a forward direction. It helps us find the actual output of each neuron. Backpropagation: In this step, we update the weights of the network based on the difference between the actual output of the network ...
