3. Which statement describes machine learning?

A It only follows fixed rules typed in by an expert

B It learns from data and improves over time

4. A question asks you to name a type of AI. Which answer would be accepted for 0478?

A Computer vision

B Machine learning

5. A medical program asks the doctor questions, applies stored rules and suggests a diagnosis. Which type of AI is it?

A Expert system

B Machine learning

Answer Key

The two types of AI in this course

Section A: Quick Questions

A — Two: expert systems and machine learning

A — It uses stored facts and rules to give advice

B — It learns from data and improves over time

B — Machine learning

A — Expert system

Section B: Match the Pairs

expert system → One of the two AI types in the course: it uses stored facts and rules to give advice or make decisions

machine learning → The other AI type in the course: it learns from data and improves its performance over time

An AI type that applies stored IF-THEN rules written from experts' knowledge → IF fever AND cough THEN flu

An AI type that improves by finding patterns in lots of training data → model = train(data)

AI types = expert system, machine learning, robotics → Robotics is wrongly listed as a third type. The course covers only two types of AI: expert systems and machine learning. Other kinds are not examined.

machine learning = fixed rules from an expert → This describes an expert system, not machine learning. Machine learning learns from data and improves, rather than only following fixed rules.

Section C: Definitions

Two types of AI: expert systems and machine learning — The 0478 course covers only two types of AI. An expert system uses stored facts and rules to give advice. Machine learning learns from data to improve. Other kinds of AI are not examined.

Section D: Fill in the Blanks

AI type 1: expert system
AI type 2: machine learning

expert system: stored facts and rules

machine learning: learns from data

numberOfAITypes ← 2

Other kinds of AI are not examined

Section E: Spot the Error

C — A system that uses stored rules and facts is an expert system, so this branch should output "Expert system". Machine learning belongs in the ELSE branch.

D — Only two types of AI are examined and only type1 and type2 exist. type3 was never declared, so the line should use type2 (machine learning).

B — An IF statement must end with THEN. The line should be IF kind = "expert system" THEN.

B — Machine learning learns from data and examples to improve. Fixed rules only describes an expert system, so the line should be learner ← "data and examples".

C — If a system adapts by learning from data, it is machine learning. This line should set type to "machine learning"; the expert system belongs in the ELSE branch.
