6.Discuss the advantages and disadvantages of instant-based learning. Explain how the memory storage can be improved when dealing with large data set.
7. If you are requested to using a clustering technique for movies data set, what type of output clusters will you choose (Separated clustered, Venn Diagram clusters, Probability table clusters, or Hierarchical clusters)? Explain
For movies data set I think the Venn diagram is good for it, because its easiest representation for movies that are in more than one category. Example, a movie that is drama and horror will be in the interception between the two clusters.
8.Using the table below:
Car | Bus | Bicycle | Motorbike | Boat |
No | Yes | No | Yes | Yes |
Yes | No | No | Yes | No |
Yes | Yes | No | Yes | No |
No | No | Yes | Yes | No |
No | Yes | No | Yes | Yes |
Yes | No | Yes | No | Yes |
Yes | Yes | No | No | No |
Yes | Yes | Yes | No | No |
No | No | Yes | No | Yes |
No | Yes | No | Yes | No |
Yes | Yes | Yes | No | No |
Yes | No | Yes | No | No |
- Calculate the support and confidence values of the following association rules:
-
- If Car = Yes , then Boat = No
Support = 6
Confidence = 6/7=85%
- If Car = Yes and Bus = Yes, then Bicycle = No and Boat = No
Support = 2
Confidence = 2/4=50%
- If Boat =No and Bicycle = No, then Car = Yes
Support = 3
Confidence = =75%
- Find an association rule with a minimum support value of 6 and a minimum confidence value of 80%.
If Bicycle = No, then Motorbike = Yes
Support = 6
Confidence = 5/6 = 83.3%
