Eryk Lewinson. Let's take a look at how many parameters are needed. The convolution kernel size is still 5 5, so there are 6 (3 5 5 + 1) + 6 (4 5 5 + 1) + 3 (4 5 5 + 1) +1 (6 5 5 + 1) = 1516 parameters. # The size of the filter used in this layer is 2 * 2, and the step length and width are both 2, so the output matrix size of this layer is 14 * 14 * 6. Yann LeCun was born at Soisy-sous-Montmorency in the suburbs of Paris in 1960. Output featuremap size: 28 * 28 (32-5 + 1) = 28, Trainable parameters: (5 5 + 1) 6 (5 * 5 = 25 unit parameters and one bias parameter per filter, a total of 6 filters), Number of connections: (5 5 + 1) 6 28 28 = 122304, Sampling method: 4 inputs are added, multiplied by a trainable parameter, plus a trainable offset. The F6 layer has 84 nodes, corresponding to a 7x12 bitmap, -1 means white, 1 means black, so the black and white of the bitmap of each symbol corresponds to a code. This results in 120 convolution results. The target values for the output units were LeNet is a convolutional neural network structure proposed by Yann LeCun et al. An Overview of LeNet. This pioneer work for image classification with convolutional neural nets was released in 1998. ---------------------------------------------------------------------------------.

Understand the LeNet-5 Convolution Neural Network :: InBlog # The number of output nodes in this layer is 120, with a total of 5 * 5 * 16 * 120 + 120 = 48120 parameters. The pooling layer of S2 is the sum of the pixels in the 2 * 2 area in C1 multiplied by a weight coefficient plus an offset, and then the result is mapped again. That’s why the number of training parameters in this layers are 1516 instead of 2400 and similarly, the number of connections are 151600 instead of 240000. # The input matrix size of this layer is 10 * 10 * 16. Here is an example of LeNet-5 in action. The LeNet-5 architecture consists of two sets of convolutional and average pooling layers, followed by a flattening convolutional layer, then two fully-connected layers and finally a softmax classifier. Note: This layer does not count as the network structure of LeNet-5. Additionally, Keras provides a facility to evaluate the loss and accuracy at the end of each epoch. This layer has a total of 32 training parameters of 2x16, 5x5x5x16 = 2000 connections.
