Human-Centered Artificial Intelligence and Machine Learning

Artificial intelligence (AI) is the study and design of algorithms that perform tasks or behaviors that a person could reasonably deem to require intelligence if a human were to do it. Broadly construed, an intelligent system can take many forms: a system designed to be indistinguishable from humans; a speech assistant such as Alexa, Siri, Cortana, or Google Assistant; a self-driving car; a recommender in an online commerce site; or a non-player character in a video game. We refer to intelligent systems as agents when they are capable of making some decisions on their own based on given goals. Machine learning (ML) is a particular approach to the design of intelligent system in which the system adapts its behavior based on data. It is the success of machine learning algorithms in particular that have lead to recent growth in commercialization of artificial intelligence. Humans are increasingly coming into contact with artificial intelligence and machine learning systems. At times it is evident, as in the case of Siri, Alexa, Cortana, or Google Assistant. It is also evident in the case of self-driving cars or non-player characters in computer games.
