Neural networks are computer systems that attempt to imitate the functioning of the human brain. They consist of neurons that are connected and process information by transmitting it through neural connections. Each neuron performs a simple function, but together they can process complex tasks.
Neural networks are important because they allow us to solve tasks that were previously impossible or very difficult to solve using traditional programming methods. They are used in various fields, including image and sound processing, speech recognition, economic trend forecasting, production process management, and much more.
Currently, neural networks are one of the key components of machine learning and artificial intelligence. They can be trained on large amounts of data and gradually improve their results, making them very useful for solving tasks that were previously inaccessible for automation.
The goal of this book is to introduce the reader to the basics of neural networks, starting with simple concepts and methods and ending with more complex topics. In the book, you will learn how neurons work, how to train neural networks, how to choose the appropriate neural network for a particular task, and how to apply neural networks to solve classification, regression, and clustering tasks.
The book is aimed at beginners and does not require any prior knowledge in the field of machine learning. It provides the reader with a complete practical guide to working with neural networks, which will help to start applying them in their own projects. By reading the book, you will acquire the necessary knowledge and practical skills for working with neural networks, as well as learn about the latest trends and developments in this field.

Chapter 1: Basics of Neural Networks
Neural networks are a powerful tool in the field of artificial intelligence and machine learning. They are used in many applications, such as speech recognition, image processing, and forecasting. However, to understand how a neural network works, one must start with the basics.
The basic unit of a neural network is a neuron. A neuron is a simple information processing unit that mimics the function of a nerve cell in our brain. A neuron receives input signals from other neurons and generates an output signal that is passed on to other neurons.
