CS 561, Lecture 1 How to achieve AI? How is AI research done? AI research has both theoretical and experimental sides. The experimental side has both basic and applied aspects. There are two main lines of research: One is biological , based on the idea that since humans are intelligent, AI should study humans and imitate their psychology or physiology. The other is phenomenal , based on studying and formalizing common sense facts about the world and the problems that the world presents to the achievement of goals. The two approaches interact to some extent, and both should eventually succeed. It is a race, but both racers seem to be walking. [ John McCarthy]

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
