Artificial Intelligence (AI) is intelligence demonstrated by machines, as opposed to intelligence displayed by humans or by other animals. It involves perceiving, synthesizing, and inferring information¹. AI technology enables a computer to think or act in a more 'human' way by taking in information from its surroundings and deciding its response based on what it learns or senses.
AI has a wide range of applications including advanced web search engines (e.g., Google Search), recommendation systems (used by YouTube, Amazon, and Netflix), understanding human speech (such as Siri and Alexa), self-driving cars (e.g., Waymo), generative or creative tools (ChatGPT and AI art), automated decision-making, and competing at the highest level in strategic game systems (such as chess and Go).
AI research has tried and discarded many different approaches, including simulating the brain, modeling human problem-solving, formal logic, large databases of knowledge, and imitating animal behavior. In the first decades of the 21st century, highly mathematical and statistical machine learning has dominated the field and has proved highly successful in solving many challenging problems throughout industry and academia¹.
