Questions from past exams

* What are the basic phases for building knowledge engineering systems?  Explain briefly three of them.

* You want to develop an intelligent system that can help you find malfunctions of your computer.  Write the rules if the computer does not start.

* How does an expert system establish the net certainty factor for conjunctive and disjunctive rules?  Give an example for each case.

* Write down a fuzzy rule.  What is the difference between classical and fuzzy rules?  Give examples.

* Suppose the knowledge base of an Expert System consists of the following rules:

Rule 1:

IF A is Y

THEN C is Z {cf 0.6}

Rule 2:

IF B is X

THEN C is Z {cf 0.8}

Calculate cf(cf1, cf2) for the following cases:

-        cf(E1)=cf(E2)=0.75

-        ..

  

* What is a conflict set of rules?  How can we resolve a conflict?  List and describe the basic conflict resolution methods.

Presentations + Assignments

Guidelines on the presentations

As stated in the last lecture, the presentations will now be scheduled towards the end of term (i.e., very soon).  Each presentation lasts ten minutes.

1. Do not copy and paste text from any source without properly citing it.
2. Limit the text on each slide and try to keep a one-idea-per-slide ratio.
3. Have about 10-20 slides in total.
4. Separate between what you say and what the slides say.
5. Get to the details quickly.
6. Please ensure that your paper is a journal paper and is related to AI and Expert Systems.

The CLIPS lab test will be worth 5 marks.

Guidelines on the test will be published soon.

In addition, I am setting a couple of assignments.

Assignment 1 (worth 2.5 marks)

Problems 4.3, 4.4, and 4.5 at the end of Chapter Four in the Giarratano and Riley textbook.

Assignment 2 will be published next week.
