AI is the study of programmed systems that can simulate, to some extent, human activities such as perceiving, thinking, learning and acting. Behavior by a machine that, if performed by a human being, would be called intelligent Fig: Turing test 7 Artificial Intelligence Natural Social Reasoning language Intelligence Artificial Knowledge Learning Intelligence representation Planning Perception Robotics 8 Three types of AI Narrow AI General AI Superintelligence • Singular task • Machine intelligence • Hypothetical agent • Successfully realized • Carry out any • Machines become to date cognitive function self-aware • Operate under a that a human can • Surpass the capacity narrow set of • Knowledge transfer of human constraints and between domains intelligence limitations • Fujitsu’s ”K” supercomputer 9 Poll 3 Go to: www.menti.com Use the code: 60 72 51 10 How Old is the idea of AI? ● Sixth-fifth century BC ● Aristotle layout the epistemological basis; introduces syllogistic logic ● The Iliad – assorted automata from the workshops of Greek god Hephaestus ● Late first century ● Fable automata built by Heron of Alexander ● Fifteenth-sixteenth century ● Mechanic clocks, Paracelus introduces a recipe for a humanculus, an intelligent “little man” ● Eighteen century ● Philosophers try to formulate the laws of thought Hoffman’s The Sandman ● Nineteenth century Goethe’s Faust ● Literary artificial intelligences proliferation Mary Shelley’s Frankenstein ● Twentieth century ● Alan Turin proposes an abstract of universal computing machine 11 AI: Past, Present and Future The Turing test Deep learning, big "I propose to consider data and general the question, 'Can 2 nd AI: 2011-present machines think?’” (A. 1987AI Winter: Goals fulfilled: Access to large 1993-2011 amounts of data Turing, 1950) -1993 Faster computers An interrogator asks Deep Blue (1997) Deep learning drives questions to an progress in image and Victory of the “neats” (unseen) person A.
