Therefore the Purity and Entropy measures are likely to improve (increased Purity , decreased Entropy ) monotonically with the number of clusters in the result, up to a degen-erate maximum where there are as many clusters as datapoints. However,clustering solutions ratedhigh by either measure may still be far from ideal.
