Write a simple definition for artificial intelligence.
Artificial intelligence, or AI, refers to the development of computer systems that are able to perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and language translation. These systems use algorithms, machine learning, and other techniques to mimic and sometimes surpass human-level intelligence in specific domains.
