What are the limitations of agglomerative clustering?
Some of the drawbacks of using agglomerative hierarchical clustering compared to other types of cluster analysis methods include: it can be computationally expensive, it does not produce the same number of clusters for different datasets, it can struggle with high-dimensional data, and it does not handle data with
What is the problem with hierarchical clustering?
One of the problems with hierarchical clustering is that there is no objective way to say how many clusters there are.
If we cut the single linkage tree at the point shown below, we would say that there are two clusters.
However, if we cut the tree lower we might say that there is one cluster and two singletons.Complete-linkage clustering is one of several methods of agglomerative hierarchical clustering.
At the beginning of the process, each element is in a cluster of its own.
The clusters are then sequentially combined into larger clusters until all elements end up being in the same cluster.
