In HC, the number of clusters K can be set precisely like in K-means, and n is the number of data points such that n>K. The agglomerative HC starts from n clusters and ... WebJul 14, 2024 · With divisive, we start with $2^N$ comparisons (because each object can be in one of two clusters) and each is more time consuming. And the costs stay high because, while each cluster gets smaller there are more of them. If you have 100 objects, then agglomerative starts with 4950 comparisons while divisive starts with $1.26*10^{30}$. coach handytasche
