What is Neural Network?
TL;DR
The most fundamental computational model in AI, inspired by the neural circuits of the human brain. The foundation of deep learning.
Neural Network: Definition & Explanation
A neural network is a computational model that mathematically mimics the connection structure of neurons (nerve cells) in the human brain, serving as the foundational technology of modern AI. It consists of input layers, hidden layers, and output layers, with neurons (nodes) in each layer connected by weighted links. During learning, the model adjusts connection weights through backpropagation to minimize the difference (loss) between predictions and correct answers. Deep neural networks with many hidden layers constitute deep learning, and Transformers are also a type of neural network. Neural networks underpin virtually all AI technologies, including image recognition, speech recognition, and natural language processing.
