2.1 Backtracking, Data Mining and Heuristics

Question 1

What is the definition of Backtracking?

Answer 1

After failing to find a solution, you return to earlier steps to try a different path/approach

Question 2

What is the definition of Data Mining?

Answer 2

Searching through data to look for patterns and correlations

Question 3

What are the steps for Data Mining?
(4 points)

Answer 3

*Look for patterns
*Look for correlations
*Often brute force algorithms
*Used to make predictions or models

Question 4

What is the definition for Heuristic problem solving?

Answer 4

Taking an educated guess rather than looking at all of the possibilities

Question 5

What is the point of Heuristic?

Answer 5

An educated guess is taken,
when it is unfeasible/ not possible to look at all eventualities,
This leads to a ‘good enough solution’.

Question 6

What is the definition of Pipelining? {2.1}
(2 points)

Answer 6

*Completing subtasks simultaneously
*Using the output from one subtask as the input to another

Question 7

What is the definition of Visualising Data?

Answer 7

Representing data virtually to make it easier to understand
