Foundations and Knowledge
- Explain why knowledge is necessary for intelligent behaviour in an
AI agent. Explain how the sensors of an AI agent can be used to
obtain that knowledge. (0.5%)
Answer
- Knowledge is used to guide the search.
- Machine learning from sensor data
- When you use Google to find information, you are given a list of web
pages to that might contain the answer. However, sometimes it is necessary
to follow a series of links from page-to-page-to-... until you find
the precise information you need. Explain why this activity requires
intelligence. (0.25%)
Answer
Pages typically have multiple links, and you have to decide which
to follow.
- The ability to solve problems is generally taken as a prime indicator
of intelligence. What kind of problems do NOT require intelligence
to solve? (0.25%)
Answer
Problems that have no choices.
- I know that Red Stripe is a good beer to drink.
I believe that if I drink a good beer then, if I don't drink too
many of them I am happy.
I know that if I don't drink too many beers then I will be sober.
I know I drink Red Stripe and I know I am sober.
What is the espistemic status of my happiness?
Show your working, noting the epstemic status of each formula derived,
and naming the type of derivation (deduction, abduction, or induction)
used in each derivation step.

Answer
- RSiG[K] +D DGB => (NtooM => H)[B] |- (NtooM => Happy)[B]
- Sober[K] +A (NtooM => Sober)[K] |- NtooM[H]
- (NtooM => H)[B] +D NtooM[H] |- Happy[B]
- Consider a KB in which the following words are available as syntax:
"University-of-the-West-Indies", "chancellor-of", "wise".
Provide a model (domain and two mappings) for the statement "The
chancellor-of the University-of-the-West-Indies is wise.".
Use UPPERCASE WORDS for domain elements. (0.5%)
Answer
- Domain = {UWI, ALLEYNE}
- F = {University-of-the-West-Indies -> UWI,
chancellor-of(UWI) -> ALLEYNE,
chancellor-of(ALLEYNE) -> ALLEYNE}
- R = {wise(ALLEYNE) -> TRUE, wise(UWI) -> FALSE}
