04 - Pattern Recognition

 1. When we decompose a complex problem we often find patterns among the smaller problems we create. The patterns are ...
If you are able to, watch the video on pattern recognition

  differences that some of the problems posesss to make them unique

  similarities that are not able to be seen under any circumstances

  similarities or characteristics that some of the problems share

  differences that cause the problems to be unsolvable

 2. Pattern recognition can be thought of as a process that involves the following steps:
Pattern recognition steps
==========================
1 - Identifying common elements or features in 
problems or systems

2 - Identifying and interpreting common differences 
between processes or problems

3 - Identifying individual elements within problems

4 - Describing patterns that have been identified

5 - Making predictions based on identified patterns

 6. Read the following excerpt and decide whether you agree.
Pattern recognition - importance
=================================
Finding patterns is extremely important. Patterns make our 
task simpler. Problems are easier to solve when they share 
patterns, because we can use the same problem-solving 
solution wherever the pattern exists.

The more patterns we can find, the easier and quicker 
our overall task of problem solving will be.

  False

  True

 7. Why do we need to look for patterns in problems?

  Patterns make it more complex and therefore more difficult to solve problems

  None of these options

  It is never useful to look for patterns - this is just an artistic, fun thing to do

  Patterns make it easier for us to solve complex problems

 8. 'All cars have wheels' is a pattern, because all cars have a _____________________ - wheels.

  different feature

  distinct colour

 9. Patterns exist among different problems and within individual problems. We need to look for both.

  TRUE

  FALSE

 10. Pattern recognition has applications in computer vision, radar processing, speech recognition and text classification.

  False

  True
