Testing is an important part of building reliable Node.js applications. When an application grows, manually checking every feature becomes difficult. A small change in one function can also break another part of the application. This is where automated testing helps. Mocha.js provides the framework for organizing and running your tests, while Chai provides expressive assertions […]
Transformers are one of the most important technologies behind modern artificial intelligence. They power many of today’s advanced AI systems, including: Before Transformers became popular, many language-processing systems relied heavily on architectures such as RNNs and LSTMs. Transformers changed this by introducing a new way to process sequences using attention mechanisms. Instead of reading information […]
When writing tests with Mocha.js, you need a way to check whether your code produces the expected result. For example, if a function should return 10, your test needs to verify that the actual result is really 10. This is where Chai comes in. Chai is an assertion library for JavaScript that can be used […]
Natural Language Processing, commonly called NLP, is a field of artificial intelligence that helps computers understand, process, analyze, and generate human language. Human language is complicated. People use: Computers, however, work with numbers and mathematical representations. NLP acts as a bridge between human language and machines. It allows computers to work with: Modern applications such […]
Asynchronous code is everywhere in Node.js applications. Whether you are calling an API, reading a file, querying a database, or using a timer, the result usually does not come back immediately. Because of this, testing asynchronous code is slightly different from testing normal synchronous functions. In this guide, you will learn how to test asynchronous […]
Image classification is one of the most popular applications of artificial intelligence and deep learning. It allows a computer to look at an image and predict what that image contains. For example, an image classification model can identify whether an image contains: Modern image classification systems are commonly built using Convolutional Neural Networks, or CNNs. […]
When building a Node.js application, writing code is only part of the job. You also need to make sure that your code works correctly. This is where unit testing becomes important. Unit testing allows you to test small parts of your application independently. Instead of testing the entire application at once, you test individual functions […]
Convolutional Neural Networks, commonly called CNNs, are one of the most important deep learning architectures used in modern artificial intelligence. They are especially powerful for working with visual data such as: CNNs are widely used in computer vision because they can automatically learn important visual features from data. Instead of manually telling a computer to […]
If you have already learned the basics of Python, NumPy, machine learning, and neural networks, the next practical step is to build your first neural network. One of the best frameworks for doing this is PyTorch. PyTorch makes it relatively easy to create neural networks, define layers, calculate loss, perform backpropagation, and train models using […]
