ThatвЂ™s not to say that the other layers are not critical, but take a backseat to this critical set of four as they define the actual architecture itself. Pooling layers ( POOL), of equal importance as CONV and FC, are also included in network diagrams as they have a substantial impact on the spatial dimensions of an image as it moves through a CNN.Д¬ONV, POOL, RELU, and FC are the most important when defining your actual network architecture. Activation and dropout layers are not considered true вЂњlayersвЂќ themselves but are often included in network diagrams to make the architecture explicitly clear. Of these layer types, CONV and FC (and to a lesser extent, BN) are the only layers that contain parameters that are learned during the training process. The SOFTMAX activation layer is often omitted from the network diagram as it is assumed it directly follows the final FC.

Here, we define a simple CNN that accepts an input, applies a convolution layer, then an activation layer, then a fully connected layer, and, finally, a softmax classifier to obtain the output classification probabilities. We often use simple text diagrams to describe a CNN: INPUT => CONV => RELU => FC => SOFTMAX.

Stacking a series of these layers in a specific manner yields a CNN.

Activation ( ACT or RELU, where we use the same or the actual activation function).

There are many types of layers used to build Convolutional Neural Networks, but the ones you are most likely to encounter include:

Finally, the output layer will be a 1 Г—1 Г—N volume, which represents the image distilled into a single vector of class scores. Neurons in subsequent layers will only be connected to a small region of the layer before it (rather than the fully connected structure of a standard neural network) - we call this local connectivity, which enables us to save a huge amount of parameters in our network. To make this example more concrete, again consider the CIFAR-10 dataset: the input volume will have dimensions 32 Г—32 Г—3 (width, height, and depth, respectively). Unlike a standard neural network, layers of a CNN are arranged in a 3D volume in three dimensions: width, height, and depth (where depth refers to the third dimension of the volume, such as the number of channels in an image or the number of filters in a layer). Instead, we can use Convolutional Neural Networks (CNNs) that take advantage of the input image structure and define a network architecture in a more sensible way. Each image in CIFAR-10 is 32 Г—32 with a Red, Green, and Blue channel, yielding a total of 32 Г—32 Г—3 = 3 ,072 total inputs to our network.ДЄ total of 3 ,072 inputs does not seem to amount to much, but consider if we were using 250 Г—250 pixel images - the total number of inputs and weights would jump to 250 Г—250 Г—3 = 187 ,500 - and this number is only for the input layer alone! Surely, we would want to add multiple hidden layers with a varying number of nodes per layer - these parameters can quickly add up, and given the poor performance of standard neural networks on raw pixel intensities, this bloat is hardly worth it. To demonstrate how standard neural networks do not scale well as image size increases, letвЂ™s again consider the CIFAR-10 dataset. Leaves much accuracy to be desired (i.e., a standard feedforward neural network on CIFAR-10 obtained only 52% accuracy).Do not scale well as the image size increases.

However, neural networks operating directly on raw pixel intensities:
