2021SC@SDUSC 0. Preface This blog post is mainly about the self attention mechanism of deep learning, qkv part and gradient in deep learning 1. Self attention mechanism of deep learning 1.1 basic concepts of self attention mechanism For the self attention mechanism, Q, K and V, that is, query, key and value, all come from the same inpu ...

Chapter VI fundamentals of visual processing 6.1 introduction to convolutional neural network          The convolution neural network is composed of one or more convolution layers and the top fully connected layer (corresponding to the classical neural network), as well as the correlation weight and Poo ...

In the last chapter, we introduced the basic principle of convolutional neural network. In this chapter, we will take you to understand the structure of modern convolutional neural network. Many studies of modern convolutional neural network are based on this chapter. Although the concept of deep neural networks is very simple - stackin ...

1 perceptron The output of the perceptron can be set to 0 or 1; Or - 1, 1. By continuously introducing data points, this line can effectively segment all kinds of training data. It is worth noting that the convergence theorem is a concept in mathematical statistics. Points cannot be taken on the plane to separate such two data (red ...

image convolution 1 cross correlation operation Strictly speaking, convolution layer is a wrong name, because the operation it expresses is actually cross-correlation operation, not convolution operation. In the convolution layer, the input tensor and kernel tensor generate the output tensor through cross-correlation operation. First, let's ...

Three methods of initializing parameters First, download the data set and necessary files required for this practice. ( Download link )Put it in the project folder established below. Then open pycharm, create a new project called improved neural network, and then create a new python file called init.py. Three initialization methods are us ...
