Agglomerative Nesting
AGNES is a Hierarchical Clustering method which uses the sinlge-link method to merge datapoints with the least Dissimilarity.

This method can be thought of like a Dendogram where we can get any desired clustering resolution by cutting the dendogram at a certain level where then each connected component forms a cluster.
Disadvantages
- Cant undo what was done previously
- Laufzeit of
