(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. Web5 de set. de 2016 · Introduction. Convolutional neural networks (CNNs) are a biologically-inspired variation of the multilayer perceptrons (MLPs). Neurons in CNNs share weights unlike in MLPs where each neuron has a separate weight vector. This sharing of weights ends up reducing the overall number of trainable weights hence introducing sparsity.
