Tomorrow’s Technology and You Chapter 15 Artificial Intelligence © 2006 Prentice-Hall, Inc. Slide 1 Chapter 15 Objectives Define artificial intelligence and discuss its most common applications. Explore Implications & Ethical Questions relating to AI © 2006 Prentice-Hall, Inc. Slide 2 What Is Artificial Intelligence? (pp 552-556) “…when computers do the things that make people seem intelligent.” who gave us this definition? when? what is wrong with it? “…the study of how to make computers do things at which, at the moment, people are better.” This definition has problems too – what are they? Is there a better definition? Pros, and cons of approaches to AI? simulation ‘brute force’ searching machine learning © 2006 Prentice-Hall, Inc. Slide 3 AI Applications Machine Translation (pp 556-557) what are ‘parsing programs’? How well do they work? what method is used today? Where on the Web? Expert Systems (p 558-564) Examples? Benefits? Possible problems? OCR (p 565-566) uses? limitations? Voice Input and output (p 566-569) uses? limitations? Possible problems? © 2006 Prentice-Hall, Inc. Slide 4 AI – Implications & Ethical Questions (pp 570-575) What are the consequences of the growing use of ‘steel-collar’ workers? What results can come from making a machine (eg ELIZA) appear human? Is this likely to be an increasing problem? MEMS and nanomachines how much is possible today? future possibilities? possible problems? “Human vs machine” What is your view of the answer to the questions on p 575? Do you believe that ‘humanity urgently needs to begin preparing’ for singularity? If so, how? If not, why not? © 2006 Prentice-Hall, Inc. Slide 5
