perceptron neural network

TensorFlow deep learning convolutional neural network CNN, tensorflowcnn I. Convolutional Neural Network Overview ConvolutionalNeural Network (CNN) was originally designed to solve image recognition and other problems. CNN's current applications are not limited to images and

In the previous article, we saw how neural networks use gradient descent algorithms to learn their weights and biases. However, we still have some explanations: we did not discuss how to calculate the gradient of the loss function. This article will explain the well-known BP algorithm, which is a fast algorithm for calculating gradients.The inverse propagation algorithm (backpropagation ALGORITHM,BP) was presented at 1970s, but its importance was not

The basic overview of neural networks and neural network models are not carefully introduced here. A detailed introduction to the introduction of the neural network and its model is presented in the details of Daniel Ng, Stanford University. This paper mainly introduces the

The content of particle swarm optimization can be obtained by searching.

The neural network is used to deal with the nonlinear relationship, the relationship between input and output can be determined (there is a nonlinear relationship), can take advantage of the neural network self-learning (need to train the data set with explicit input and output), training after the weight value determi

BP (backward propogation) neural networkSimple to understand, neural network is a high-end fitting technology. There are a lot of tutorials, but in fact, I think it is enough to look at Stanford's relevant learning materials, and there are better translations at home: Introduction to Artificial neural

BP (Back Propagation) network is a multi-layer feed-forward Network trained by the error inverse propagation algorithm, which was proposed by a team of scientists led by Rumelhart and mccelland in 1986, it is one of the most widely used neural networks. The BP network can learn and store a large number of input-output

Straight into the subject, the first thing to be sure is that the application of the Rosenblatt Perceptron is a linear sub-model ( popularly speaking is that in n-dimensional space There is a super-plane can be divided into the entire model ) its role is classification, by an adjustable synaptic weight and bias of the neuron composition.Mode: The standard style of a transaction.Perceptron: Perceptron model

The role of cross-entropy One of the most common ways to solve multi-classification problems with neural networks is to set N output nodes at the last layer, whether in shallow neural networks or in CNN, for example, the last output layer in alexnet has 1000 nodes:And even if the ResNet cancels the all-connected layer, it will have a 1000-node output layer at the end: In general, the number of nodes in the
