Neural networks: what they are and how they work

Neural networks

Neural networks are one of the most popular and promising methods of machine learning. They mimic the work of the human brain and are able to solve complex problems that were not subject to other methods.

Definition of Neural Networks

A neural network is a system consisting of a large number of simple elements called neurons. Neurons are connected to each other, forming a network. Each neuron processes information from other neurons and produces its own signal. The signals of all neurons are summed up, and the result of the summation is fed to the output of the network.

The Importance of Neural Networks

Neural networks have great potential for solving various problems in various fields, including:

  • Pattern recognition
  • natural language processing
  • Prediction
  • Management
  • Medicine
  • Finance
  • Winemaking

History of the development of neural networks

The idea of ​​creating neural networks originated in the 1940s. However, the first real neural networks were created only in the 1960s. In the 1980s, there was a new surge of interest in neural networks associated with the development of personal computers. In the 1990s, neural networks began to be used in various fields, including pattern recognition, natural language processing, and prediction.
