What is the purpose of neural networks?

The primary purpose of neural networks is to model and solve complex problems by mimicking the functioning of the human brain. Neural networks are designed to recognize patterns and relationships in data, enabling tasks such as classification, regression, and prediction. For instance, in image classification, convolutional neural networks (CNNs) extract features like edges and textures to identify objects within images. Neural networks are versatile and have been successfully applied to tasks across domains, such as natural language processing (e.g., GPT models), reinforcement learning (e.g., AlphaGo), and generative modeling (e.g., GANs). They are particularly effective for problems where traditional rule-based approaches struggle, as they can learn directly from data without requiring explicit programming of rules.
