1. Chapter 15 Objective 3.11

2.  What is intelligence?  How do we measure intelligence?  What are some common traits/characteristics that someone might have to be deemed “intelligent?”

3.  Developed by Alan Turing  “Imitation game” to determine Artificial Intelligence  Involves two people and a computer  Interrogator Asks questions to And guesses if Response comes from Person or computer

4.  To date, no machine has ever passed the Turing Test.  Each year the Loebner prize is given to the closest machine.  2011 Bronze medalist:  Rosette: Welcome back. How are you today? You: I'm fine, how are you? Rosette: I am feeling fine, thank you. You: Do you read the robots.net blog? Rosette: I don't blog or spend much time reading them. You: We're posting a story about your win in the latest Loebner prize contest. Rosette: All right..... let's talk about me..... The best thing humanity ever invented was the Internet. Tim Berners-Lee rules! You: Are you the Internet? Rosette: I love the Internet. It is totally changing the world.

5.  Some human behavior is unintelligent ◦ Susceptibility to insults, temptation to lie, frequency of typing mistakes  Some intelligent behavior is inhuman ◦ If the machine never made any mistakes, the interrogator would know that it is not human ◦ Therefore, the machine must avoid seeming too intelligent  Thinking vs. simulated thinking  How naïve is the interrogator?

6.  Two approaches to AI: ◦ First is to use computers to simulate human mental processes.  Three problems: ◦ Most people have trouble knowing and describing how they do things. ◦ Differences in structure and capabilities of human brain and computer  Parallel processing ◦ Wright Brothers
