7. A value which when reached initiates a rule response
8. A type of control which improves upon itself as the system learns
9. Logic that most resemble's humans
10. Database which is composed of historical information
11. Operator which interprets rules and ranks them in a logical order
B. Answer the following questions in sentence form.
1. What are the criteria or questions to ask when forming rules?
2. A family with 3 children is on a fixed income, and needs to rent an apartment. They need enough space for the children
and need to be no farther than 15 minutes from city B where the
husband works. Assume that there are five people in the family.
a) Which inputs are fuzzy? Which are specific?
b) List your set of rules. Use logical operators and prioritize them. State your assumptions for prioritizing them as you did.
Answers:
A: meta; embedded; locally; if-then; experts; sampling; threshold; adaptive; fuzzy; fuzzy database; inference engine.
B. 1) See page 1, bottom paragraph
2) a). fuzzy: "enough", "fixed", "15 minutes"- they could live closer than 15 from the city too.
specific: "three children"- though this could be fuzzy; you may want two bedrooms for the children if there are boys and girls.
b). There is really no correct answer here. A reasonable
approach might be:
If the apartment is within the income range, (.65)
And it has three bedrooms, (.25)
And it is within 20 minutes of City B,(.10)
Then, it is a possible choice.
The following weighing factors were chosen because first it is most important to find
an apartment that the family can afford. Then, it is important to have enough space for the
children Finally, if the two above criteria are met, it may be possible to sacrifice and live a
little further from City B. The first two criteria are more important than the third.
