convolutional neural Networks:step by step Welcome to Course 4 ' s-A-assignment! In this assignment, you'll implement Convolutional (CONV) and pooling (POOL) layers in NumPy, including both forward pro Pagation and (optionally) backward propagation. notation: We assume that you are already familiar with numpy and/or have completed the previous courses. Let ' s g

Recently has been looking at convolutional neural network, want to improve the improvement to make something new, read a lot of papers, wrote a review of Deep learning convolutional neural Network has some new understanding, and s

convolutional neural Network Origin: The human visual cortex of the MeowIn the 1958, a group of wonderful neuroscientists inserted electrodes into the brains of the cats to observe the activity of the visual cortex. and infer that the biological vision system starts from a small part of the object,After layers of abstraction, it is finally put together into a pro

low)Going deeper Through the Network　　A Classic CNN Architecture would look like this:ReLU, Conv, ReLU, ReLU, Conv, ReLU, pool, Fully, Conv, CTED Layer(ReLU: Activation function, pool: pooling layer)There ' re other layers that is interspersed ( embellishment, scatter ) between these conv layers, they provide nonlinearities (ReLU) and preservation ( Dimension protection ) of dimension (Pool) that help to improve the robustness ( robustness ) of the

. The C5 is still labeled as a convolutional layer rather than a fully-connected layer, because if the input of LeNet-5 is larger and the others remain the same, then the dimension of the feature map will be larger than 1*1. The C5 layer has 48,120 training connections.The F6 layer has 84 units (The reason why this number is chosen is from the design of the output layer) and is fully connected to the C5 layer. There are 10,164 parameters that can be t

the composition of a convolutional neural network Image classification can be considered to be given a test picture as input Iϵrwxhxc Iϵrwxhxc, the output of this picture belongs to which category. The parameter W is the width of the image, H is the height, C is the number of channels, and C = 3 in the color image, and C = 1 in the grayscale image. The total num

Weight sharing the word was first introduced by the LENET5 model, in 1998, LeCun released the Lenet network architecture, which is the following:Although most of the talk now is that the 2012 Alexnet network is the beginning of deep learning, the beginning of CNN can be traced back to the LENET5 model, and its features are widely used in the study of convolutional
