Also consider two different clustering schemes: (1) where Cluster 1 contains records {1, 2, 3} and Cluster 2 contains records {4, 5, 6} and (2) where Cluster 1 contains records {1, 6} and Cluster 2 contains records {2, 3, 4, 5}. Which scheme is better and why?
Assignment 5
- Consider the following set of two-dimensional records:
| Record ID | Dimension1 | Dimension2 |
| 1 | 8 | 4 |
| 2 | 5 | 4 |
| 3 | 2 | 4 |
| 4 | 2 | 6 |
| 5 | 2 | 8 |
| 6 | 8 | 6 |
Also consider two different clustering schemes: (1) where Cluster 1 contains records {1, 2, 3} and Cluster 2 contains records {4, 5, 6} and (2) where Cluster 1 contains records {1, 6} and Cluster 2 contains records {2, 3, 4, 5}. Which scheme is better and why?
- Use the following table which contains five sample items with distance between the elements indicated in the table entries.
| Item | A | B | C | D | E |
| A | 0 | 1 | 2 | 2 | 3 |
| B | 1 | 0 | 2 | 4 | 3 |
| C | 2 | 2 | 0 | 1 | 5 |
| D | 2 | 4 | 1 | 0 | 3 |
| E | 3 | 3 | 5 | 3 | 0 |
- Draw single link hierarchical clustering dendrograms. The dendrograms should clearly show the order in which the points are merged.
