Question 7

What is AI?

Answer 7

A branch of computer science that deals with the simulation of intelligent human behavior by a computer.

Question 8

What are expert systems?

Answer 8

A form of AI that is developed to mimic human knowledge and experiences. They use knowledge and inference to solve problems.

Question 9

What are the advantages of an Expert System

Answer 9

• High level of expertise
• High accuracy
• Consistent results
• Ability to store large amounts of information

Question 10

What are the disadvantages of an expert system?

Answer 10

• User of the system need lots of training
• High maintenance costs
• User can make assumption that the system is infallible

Question 11

What is a user interface?

Answer 11

Method in which the user interacts with the expert system

Question 12

What is an inference engine?

Answer 12

It acts like a search engine that searches the knowledge base for information that matches the user’s query. It’s responsible for asking questions that will help it determine an answer.

Question 13

What is a knowledge base?

Answer 13

It’s a repository of facts. It stores knowledge about an area of expertise obtained from a source.

Question 14

What is a rules base?

Answer 14

It’s a set of inference rules. These are used by the inference engine to draw conclusions. Usually involve “if” statements.

Question 15

What are the steps to set up an expert system?

Answer 15

1. Information needs to be gathered from external resources to populate a knowledge base
2. A rules base must be created so that the inference engine can draw conclusions
3. The inference engine itself needs to be set up.
4. A user interface needs to be set up so that the user can interact with the expert system

Question 16

What is machine learning?

Answer 16

It’s a subset of AI in which algorithms are trained to learn from their past experiences and examples.

Question 17

What are the benefits of machine learning?

Answer 17

• They can make predictions and decisions based of previous outcomes
• They are fast and accurate
• Can analyze considerable amounts of data
