Artificial Intelligence By John Debovis & Keith Bright

What is Artificial Intelligence? • Artificial intelligence (AI) is the field of computer science that seeks to build autonomous machines—machines that can carry out complex tasks without human intervention. • Research in AI is concerned with producing machines to automate tasks requiring intelligent behavior.

Intelligent Agents • An agent is a device that responds to stimuli from its environment. • An agent could be a robot, an autonomous plane, a character in a video game, or a program commuting over the Internet. • The goal of Artificial Intelligence is to build agents that behave intelligently.

Turing Test • Can Machines Think? – Turing Test was a test designed in the 1950’s to solve this question. • Layout • A human interrogator sits in a room and uses a computer terminal to communicate with two respondents, A and B. • The interrogator knows that one respondent is human and the other is computer. • After having a conversation with A and B, the human must decide which respondent was the computer. • Is it a good test for intelligence? • Some argue that the Turing Test doesn’t demonstrate that a computer understands language

Turing Test Equivalence • Weak Equivalence – A computer that passes the Turing test would demonstrate weak Equivalence, meaning that the two systems are equivalent • Strong Equivalence – Indicates that two systems use the same internal processes to produce results • Some AI researchers assert that the true artificial intelligence will not exist until we have achieved strong equivalence • Chatbots/Eliza programs have been developed for the Turing Test

Strong AI vs. Weak AI • The assumption that machines can be programmed to exhibit intelligent behavior. • Accepted to varying degrees by a wide audience • Strong AI • The assumption that machines can be programmed to possess intelligence and consciousness. • Widely debated • Opponents of Strong AI argue that a machine is inherently different from a human and can never think about itself the same a human does.

Robotics • Robotics is the study of physical, autonomous agents that behave intelligently. • The development of faster, lighter weight computers has lead to greater research in mobile robots that can move about. • ASIMO • Despite great advances, most robots are still not very autonomous. They rely on human operators for intelligence.

Current Progress • Researched aspects of AI • Looked in programming examples and how they can be used with ELIZA • Investigated how ELIZA operates and relates to Turing Test

ELIZA • ELIZA is a famous program which rephrases many of the user's statements as questions and poses them to the user. • Example – The response to "My head hurts" might be "Why do you say your head hurts? " The response to "My mother hates me" might be "Who else in your family hates you? " • We plan on developing our own intelligent agent that is similar to ELIZA. • Example
