What is a Neural Network?

A neural network is a type of artificial intelligence (AI) that is modeled after the way the human brain works. It is composed of interconnected layers of artificial neurons (also known as nodes) that are designed to detect patterns and correlations in input data, and to adjust their weights and thresholds accordingly. Neural networks are used for a wide variety of tasks, such as recognizing patterns in images, predicting stock prices, and classifying text. They can learn and adapt to new situations, and are often used as part of larger AI systems.
