Input, hidden and output layers of a neural network

Convolutional Neural Networks (CNN)
CNNs were developed in 1988. They are optimal for working with images and videos. They analyze data piece by piece, highlighting key elements such as object boundaries. This allows neural networks to recognize faces, classify objects, or analyze visual information. CNNs are indispensable in computer vision, medical image interpretation, and image generation.
How does a neural network work?
A neural network processes data through several layers of nodes that operate australia phone number list sequentially. Thus, each layer performs its task: receives information, performs calculations, and passes the results on. This process is the basis for the operation of neural networks of any type.
Any neural network has three main types of layers: input, hidden and output. The input is raw data. This can be images, text or other types of information. The first hidden layers perform complex calculations, filtering and analyzing the input data, detecting patterns and dependencies. Depending on the architecture, there may be several such layers, each responsible for its own part of the task. Then the final result appears at the output - for example, image classification or a response to a request.
The process of training a neural network
In order for a neural network to learn how to solve problems, it needs to be trained on a huge amount of data. The machine learning process consists of several cycles, where the network adjusts internal parameters to improve the accuracy of decisions. For example, a set of images is loaded, where each image is labeled. The neural network predicts what is depicted in the photo. If the result is incorrect, the network adjusts the connections between the nodes and tries again. This method is repeated until the accuracy is satisfactory. The more data is used in the training stage, the more accurate the results.
