This is the fifth article of graph algorithm: illustration: how to understand “Relaxation” or “Relaxation” of the shortest path? The purpose of the shortest path problem is to find the path with the least cost from one vertex to another.Shortest path algorithmIt is widely used to solve various complex problems, such as finding the shortest […]

Abstract:Deep neural network is based on calculus and some statistics. Deep neural network (DNN) is essentially composed of multiple connected perceptrons, one of which is a single neuron. We can regard artificial neural network (ANN) as an input system with a group of inputs fed along a weighted path. These inputs are then processed and […]

Basic concepts of graph Definition of graph A graph G consists of a vertex set V and an edge set E, denoted as g = (V, e), where V (g) denotes a finite nonempty set of vertices in G and E (g) denotes a set of relationships (edges) between vertices in G. Note: linear table […]

Load balancing is used to solve the problem of how to select the upstream server to process the user‘s request. Here we mainly introduce several load balancing algorithms.1、round-robin：Polling, the default load balancing algorithm, which forwards the request to the upstream server in the way of polling. With the weight configuration, the weight based polling […]

Recently, I saw a very good quality translation of “neural network course that Xiaobai can understand: from principle to optimization is so simple”, like a treasure. After close reading, I found that some translations were not in place. Then I turned to the original text and read it again. I felt that the original text […]

Gradient centered GC makes the weight gradient zero mean, which can make the training of the network more stable, and can improve the generalization ability of the network. The algorithm is simple. The theoretical analysis of this paper is very sufficient, which can well explain the principle of GC Source: Xiaofei’s algorithm Engineering Notes official […]

Whenever we train our own neural network, we need to pay attention to what is called neural networkgeneralizationThe problem. In essence, this means how good our model is in learning from given data and applying the information to other areas. When training the neural network, there will be some data on the neural networkTraining,Some data […]

On the basis of summarizing the traditional activation function and attention mechanism, this paper interprets an activation function under attention mechanism, namely adaptive parametric corrector linear unit (aprelu). 1. Activation function Activation function is an important part of artificial neural network, its function is to realize the nonlinearity of artificial neural network. We first introduce […]

The second question is explained! Maybe it’s the last question before retirement (it seems that only two articles have been written in all) No, topic: Question surface Meaning of the title: There are t data There is a tree (to ensure that all nodes are connected) and there are n nodes. Each node has its […]
