neuronnät

Neuronnät, also known as artificial neural networks, are computational models inspired by the structure and function of biological neural networks found in animal brains. They are a core component of machine learning and artificial intelligence, enabling computers to learn from data and perform complex tasks.

A fundamental unit of a neuronnät is the artificial neuron, often called a node or perceptron. These neurons are interconnected and organized in layers. Typically, there is an input layer that receives raw data, one or more hidden layers where computations occur, and an output layer that provides the result. Each connection between neurons has an associated weight, which is adjusted during the learning process.

The process of learning in a neuronnät involves presenting the network with a large dataset. The network processes this data, and its internal weights are iteratively modified to minimize the difference between its predictions and the actual outcomes. This adjustment is often achieved through algorithms like backpropagation.

Neuronnät are versatile and have a wide range of applications. They are used in image and speech recognition, natural language processing, forecasting, recommendation systems, and even in scientific research for pattern discovery. The complexity and capabilities of neuronnät can vary significantly, from simple models to deep neural networks with many hidden layers.
