a) What is the disadvantage of a fully-connected neural network compared to a convolutional neural network with the same size layers? [2 MARKS] b) What are the benefits of using rectified linear units compared with the typical sigmoid activation function? [4 MARKS] (c) Suppose we have a 44 matrix shown below, which represents a feature map from one layer from CNN. Define a 22 filter that we will run over the feature map. Let the stride be 2 (meaning the (dx,dy) for stepping over the feature map will be (2,2) )
