Question

Which of the following method is used for finding the optimal of a cluster in the K-Mean algorithm?

Select the correct answer from below options:

A. Elbow method

B. Manhattan method

C. Ecludian method

D. All of the above

E. None of these

Answer 1

Answer: (A)

Out of the given options, only the elbow method is used for finding the optimal number of clusters. The elbow method looks at the percentage of variance explained as a function of the number of clusters: One should choose a number of clusters so that adding another cluster doesn’t give a much better modeling of the data.
