#### **4.1 The basics of artificial intelligence**

Artificial intelligence (AI) is defined as the simulation of human intelligence in machines programmed to think and learn like humans. The aim of AI is to create machines with the ability to perceive their environment, reason with it and act in such a way that would normally require human intelligence or to process data whose scale exceeds what humans can analyze [14]. In other words, to create systems that have a certain degree of autonomy [15]. Within the framework of autonomy in AI there is a hierarchy, comprised of three main tiers:

#### *4.1.1 Artificial narrow intelligence*

Systems designed to perform a specific task or solve a specific problem. As such, they have a narrow range of parameters allowing them to simulate human behaviors in specific contexts such as face or speech recognition and processing, voice assistance, or autonomous driving. They are "intelligent" only within the specific task they are programmed to do.
