# 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`

similarities or characteristics that some of the problems share

differences that some of the problems posesss to make them unique

similarities that are not able to be seen under any circumstances

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.```

True

False

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

None of these options

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

Patterns make it easier for us to solve complex problems

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

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

similar feature

gearbox

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
