Article Introduction：Graph neural network is a type of neural network model designed to handle graph data analysis and graph data mining tasks. It can be used for multi-label classification tasks. In graph neural networks, nodes and edges can be represented as vectors or tensors, and the relationships between nodes and edges are learned through the computational process of the neural network. In order to improve the accuracy of the network's output results, the backpropagation algorithm can be used for optimization. Multi-label classification is a method of dividing data into several different categories, where each data point can belong to more than one category. In graph data analysis, multi-label classification can be used to identify labels of nodes or subgraphs, such as the interests and hobbies of users in social networks, the properties of chemical molecules, etc. The application of graph neural networks in multi-label classification tasks has broad application prospects. 1.

Article Introduction：Naive Bayes and decision trees are common machine learning algorithms used for classification and regression problems. They are both classifiers based on probabilistic models, but their implementation and goals are slightly different. Naive Bayes is based on Bayes' theorem, assuming that features are independent of each other, and classifying by calculating the posterior probability. The decision tree classifies based on the conditional relationship between features by building a tree structure. Naive Bayes is suitable for problems such as text classification and spam filtering, while decision trees are suitable for problems where there is an obvious relationship between features. In short, Naive Bayes is more suitable for high-dimensional features and small sample data. 1. Different basic principles. Naive Bayes and decision trees are classifiers based on probability theory. Naive Bayes uses Bayes' theorem to calculate the probability of a class given the features. decision tree

Article Introduction：Transformer was originally designed for natural language processing tasks, but has now been widely used in vision tasks. Visual Transformer has demonstrated excellent accuracy in multiple visual recognition tasks and achieved state-of-the-art performance in tasks such as image classification, video classification, and object detection. A major drawback of Visual Transformer is its high computational cost. Typical convolutional networks (CNN) require tens of GFlops to process each image, while visual Transformers often require an order of magnitude more, reaching hundreds of GFlops per image. When processing video, this problem is even more severe due to the huge amount of data. The high computational cost makes visual Transformer

Article Introduction：Title: Methods to use Go language to improve function efficiency In Go language programming, optimizing function efficiency is an important aspect of improving program performance. Through reasonable design and optimization, we can make functions run more efficiently. This article will introduce some methods of using Go language to improve function efficiency, and give specific code examples. 1. Avoid frequent creation of temporary variables. In the Go language, frequent creation of temporary variables will increase the burden of memory allocation and garbage collection, thus affecting program performance. To avoid this, you can define the variable outside the function and

Article Introduction：RESTfulAPI contains two main concepts: resources and representation. A resource can be any object associated with data, or identified by a URI (multiple URIs can reference the same resource), and can be manipulated using HTTP methods. Representation is the way a resource is displayed. In this tutorial, we will cover some theoretical information about RESTful API design and implement a sample blog application API using NodeJS. Resources Choosing the right resources for a RESTful API is an important part of the design. First, you need to analyze your business domain and then decide on the amount and type of resources to use that are relevant to your business needs. If you are designing a blogging API, you might work with posts, users, and comments. these are

Article Introduction：HederaHashgraph: Innovation in Distributed Ledger Technology HederaHashgraph is a distributed ledger technology (DLT) with high throughput, low latency and strong security. Its goal is to provide a fast, secure and scalable platform for different types of applications. HederaHashgraph uses a unique consensus mechanism called the gossip protocol, which is different from traditional blockchain technology. This protocol allows nodes to reach consensus quickly and reliably through random communication, with each node only needing to exchange information with a few other nodes. In this way, transactions can propagate quickly and effectively prevent forks. The design of the Gossip Protocol enables the network to achieve efficient consensus while ensuring security and reliability.

Article Introduction：Imagine a city that thinks for itself, ensuring goods arrive as soon as possible, by "diverting" traffic so emergency vehicles can reach their destinations smoothly, and even reuniting people with their lost pets. The prospect of being called a "cognitive city" is The rewritten direction for the next generation of smart cities reads as follows: The first smart cities can sense but not act, but cognitive cities will sense and react. The key to achieving this goal is sensors distributed on the streets and edge computing. Many of the smart cities of the future will be "greenfields": entirely new cities, built from the ground up and infused with intelligence, with edge computing built into everything from streetlights to trash cans. For the people who live in these cities, edge computing will bring real, measurable improvements to their lives – starting from

Article Introduction：Case issues in MySQL Case issues in MySQL can be traced back to the design of the database. In MySQL, identifiers (such as table names, column names, variable names, etc.) are case-sensitive. This can cause us a lot of trouble in some cases. For example, when we create a table, we specify a table name of student. If we later use the SELECT statement to query the table, we cannot use Student or STUDENT or other similar case forms, otherwise the MySQL database will return an error message. How to use the BINARY keyword for case queries in MySQL. When making queries, use the BINARY keyword to make MySQL case-insensitive. For example,

Article Introduction：Convolutional neural networks perform well in image denoising tasks. It utilizes the learned filters to filter the noise and thereby restore the original image. This article introduces in detail the image denoising method based on convolutional neural network. 1. Overview of Convolutional Neural Network Convolutional neural network is a deep learning algorithm that uses a combination of multiple convolutional layers, pooling layers and fully connected layers to learn and classify image features. In the convolutional layer, the local features of the image are extracted through convolution operations, thereby capturing the spatial correlation in the image. The pooling layer reduces the amount of calculation by reducing the feature dimension and retains the main features. The fully connected layer is responsible for mapping learned features and labels to implement image classification or other tasks. The design of this network structure makes convolutional neural networks useful in image processing and recognition.
