Use the similarity matrix in Table 8.1 to perform single and complete link hierarchical clustering. Show your results by drawing a dendrogram. The dendrogram should clearly show the order in which the points are merged.
(b) Do both sets of centroids represent stable solutions; i.e., if the K-means
algorithm was run on this set of points using the given centroids as the
starting centroids, would there be any change in the clusters generated?
(c) What are the two clusters produced by single link?
(d) Which technique, K-means or single link, seems to produce the “most
natural” clustering in this situation? (For K-means, take the clustering
with the lowest squared error.)
(e) What definition(s) of clustering does this natural clustering correspond
to? (Well-separated, center-based, contiguous, or density.)
(f) What well-known characteristic of the K-means algorithm explains the
previous behavior?
