Question: Suppose that for a data set There are m points and K clusters, Half the points and clusters are in more dense regions,

Suppose that for a data set

• There are m points and K clusters,

• Half the points and clusters are in “more dense” regions,

• Half the points and clusters are in “less dense” regions, and

• The two regions are well-separated from each other. Which of the following should occur to minimize the squared error when finding K clusters:

(a) Centroids should be equally distributed between more dense and less dense regions.

(b) More centroids should be allocated to the less dense region.
