O Deep Learning emerged, allowing neural networks to process a lot of data. This makes neural networks capable of performing precise tasks. For example, it helps with fraud detection and weather forecasting.

How do neural networks work?

Neural networks have artificial neurons. These are softwarealso known as "we". They work together in a interconnected architecture. This helps with troubleshooting using computers.

When a "node" receives a stimulus, it activates. It then produces a response, which is the expected result.

Layers of neural networks

A simple neural network model has three layers. They are connected by nodes. These neural network layers do specific tasks. They work together to process information and arrive at final results.

Input layer

A input layer receives data from the outside world. It processes this information with the help of the "nodes". It then passes on these initial stimuli to the next layers.

Hidden layer

A hidden layer picks up information from the other hides or from the input. It makes a more detailed analysis of the data. This helps the network recognize patterns. It greatly improves its ability to understand information.

Output layer

A output layer presents the final result. It transforms the information from the previous stages into something conclusive.

Importance of neural networks
