33
Q

What is AI

A

Artificial intelligence is a branch of computer science dealing with the simulation of intelligent human behaviour by a computer

34
Q

How does AI work

A

they contain rules and data
they are able to reason( take data and apply it to different situations)
since they can reason they can also use old information to adapt and make predictions by seeing patters

35
Q

expert systems

A

a computer system that mimics the decision making ability of a human
use AI to simulate the judgement and behaviour of humans

36
Q

what is machine learning

A

training computers with sample data so that they can go on to make predictions about new data

37
Q

components of expert systems

A

have a knowledge base, a rule base, an inference engine and an interface

38
Q

what does machine learning have the ability to do

A

automatically adapt its own processes or data

39
Q

advantages of expert systems

A

high accuracy
results are consistent
can store vast amounts of ideas and facts
fast response times

40
Q

disadvantages of expert systems

A

needs considerable training time to ensure the system is used correctly
costs are high
only as good as the information entered

41
Q

what is the inference engine in expert systems

A

acts like a search engine that examines the knowledge base

42
Q

what is the knowledge base in expert systems

A

stores all the data and facts

43
Q

what are inference rules and where are they stored in expert systems

A

in the rules base
used by the inference engine to draw conclusions

44
Q

difference between machine learning and expert systems

A

expert systems are machines that are capable of thinking like humans
machine learning is when machines are able to learn through data acquisition and solve new problems
