Artificial intelligence and expert systems can be used to both simulate human mental processes and allow computers to think independently. Expert systems are applications that do not require common sense, are generally well understood, can be described objectively, and where human expertise is scarce. While expert systems have advantages like permanent expertise and consistent results, they also have disadvantages like a lack of common sense and inability to explain logic. People and machines each have their own strengths when it comes to decision making.

1. Artificial Intelligence and Expert Systems By: Kate Festa

2. How is AI really used? How can we benefit both today and in the future? What are the Strengths and Weaknesses ?

3. Let’s go!

4. What is Artificial Intelligence? Simple enough?

6. Rosie can… Walk Talk Care for children Clean Think independently Use emotion (relatively)

7. We have ourselves a conundrum…

8. "The aim of Artificial Intelligence is to create intelligent machines and through this, to understand the principles of intelligence. At the moment, we can settle for creating less stupid machines.” -John L. Gordon

9. “ Artificial intelligence is that attempt to make computers do what they do in movies” -Astro Teller

10. Two Distinct Ideas 1. Using computers to simulate human mental processes 2. Using computers to think independently of the way people think

12. So what’s an expert system anyway?

13. Applications Medicine Chemistry Geology Meteorology Computer Systems

16. An analogy

17. The Knowledge Base: The Library

18. The Knowledge Engineer: The Real Brain

19. The Interference Engine: The Logic

20. Human Interference: The Necessity

21. Decision Support Don’t trust a machine to make a full decision? Can’t remember everything and need a little help? Want to be reminded of situations to consider? … decision support is for you!

22. Decision Making Are you unfamiliar with a particular area? Don’t want to hire a real expert? Don’t want an industrial disaster? … a decision making system is for you! Have smaller decisions to make?

23. Human or Expert System??

24. MYCIN Better than Stanford graduates since 1970

25. IF the infection is a primary bacteremia AND the site of the culture is a sterile site AND the suspected portal of entry is the gastrointestinal tract THEN there is suggestive evidence (.7) that the infection is bacterioid

26. Advantages Permanent expertise Expertise easily reproduced Consistent Results Can hold significant amounts of information Inexpensive Consider transactions that humans overlook

27. Disadvantages Lack of human common sense Difficult to promote creative responses Cannot explain logic No response Lack of flexibility

28. People and Machines

29. Reliability
