Artificial Intelligence ( AI ) is the simulation of human Intelligence processes by machines, especially computer systems. Specific natural expert systems, natural language processing, speech recognition and machine vision. 

AI requires a foundation of specialized hardware and software for writing and training machine learning algorithms. No one programming language is synonymous with AI, but a few, including python, R and Java are popular.

In general, AI system work by ingesting large amount of labeled training data, analyzing the data for correlations and patterns, and using these patterns to make predictions about future state. In this way, a chatbot that is feed a examples of text chats can learn to produce lifelike exchanges with people, or an image recognition tool can learn to identify and describe objects in image by reviewing millions of examples.

AI programming focuses on three cognitive skills: learning and self-correction.
