the local feature is extracted, the position relationship between it and other features is determined; s layer is the feature map layer, and each computing layer of the network is composed of multiple feature mappings. Each feature is mapped to a plane, and the weights of all neurons on the plane are equal. The feature mapping structure uses the sigmoid function which affects the function core as the activation function of convolutional network, whic

1.computer Vision CV is an important direction of deep learning, CV generally includes: image recognition, target detection, neural style conversion Traditional neural network problems exist: the image of the input dimension is larger, as shown, this causes the weight of the W dimension is larger, then he occupies a larger amount of memory, calculate W calculation will be very large So we're going to intro

1. Introductionconvolutional Neural Networks (convolutional neural Networks, CNN) are sensitive to only parts of the field of vision that are affected by cells on the retina, a part of which is known as the sensation domain (receptive field ).

Turn from: The Heart of the machine Introduction Frankly speaking, I can't really understand deep learning for a while. I look at relevant research papers and articles and feel that deep learning is extremely complex. I try to understand neural networks and their variants, but still feel difficult. Then one day, I decided to start with a step-by-step basis. I break down the steps of technical operations

Take two anchor boxes for example, originally 3*3*8 become 3*3*2*8.9.YOLO Algorithm Before learning the basic elements of target detection, these elements can be combined to form the YOLO algorithm:-Input x (100*100*3), divide it into 3*3grid mesh, target Class 3 to

full connection between S4 and C5. 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
