How do you choose a number of clusters in unsupervised learning?
Hierarchical clustering has a couple of key benefits: There is no need to pre-specify the number of clusters.
Instead, the dendrogram can be cut at the appropriate level to obtain the desired number of clusters.Is there no need to specify number of clusters in hierarchical clustering?
Hierarchical clustering is also a good choice when the number of samples is small, because it does not require the number of clusters to be specified in advance like some other algorithms do.
Which clustering algorithm does not require specifying the number of clusters in advance?
A.
The elbow method is a technique used in clustering analysis to determine the optimal number of clusters.
It involves plotting the within-cluster sum of squares (WCSS) for different cluster numbers and identifying the “elbow” point where WCSS starts to level off.
