Neural network

A neural network is a group of interconnected units called <a href="/facts/Neurons/G7CyTVdH">neurons</a> that send signals to one another. Neurons can be either <a href="/facts/Cell_(biology)/bLM9UQvy">biological cells</a> or <a href="/facts/Mathematical_model/CGhyuxgz">mathematical models</a>. While individual neurons are simple, many of them together in a network can perform complex tasks. There are two main types of neural network.

<ul><li>In <a href="/facts/Neuroscience/o5RV8Cas">neuroscience</a>, a <a href="/facts/Biological_neural_network/pgngqMLf">biological neural network</a> is a physical structure found in <a href="/facts/Brain/EKla9NkJ">brains</a> and complex <a href="/facts/Nervous_system/CDxRKU2U">nervous systems</a> – a population of nerve cells connected by <a href="/facts/Synapse/vdMRJCUn">synapses</a>.</li>
<li>In <a href="/facts/Machine_learning/e0w0XJTu">machine learning</a>, an <a href="/facts/Neural_network_(machine_learning)/6V1jMlkx">artificial neural network</a> is a mathematical model used to approximate <a href="/facts/Nonlinear_function/4aYItALC">nonlinear functions</a>. Artificial neural networks are used to solve <a href="/facts/Artificial_intelligence/lJGauQwX">artificial intelligence</a> problems.</li></ul>
