dendrogram hierarchical clustering

What are the two 2 types of hierarchical clustering?
UPGMA (Unweighted Pair Group Method using arithmetic Averages) is arguably the most popular hierarchical clustering algorithm in use to date, especially for gene expression (D'haeseleer, 2005) and for protein sequence clustering (Liu and Rost, 2003).
What is the data structure of a dendrogram?
Plot the hierarchical clustering as a dendrogram.
The dendrogram illustrates how each cluster is composed by drawing a U-shaped link between a non-singleton cluster and its children.
The top of the U-link indicates a cluster merge.
The two legs of the U-link indicate which clusters were merged.
What is the best algorithm for hierarchical clustering?
A dendrogram is a tree-like structure that explains the relationship between all the data points in the system.
However, like a regular family tree, a dendrogram need not branch out at regular intervals from top to bottom as the vertical direction (y-axis) in it represents the distance between clusters in some metric._{7 mai 2021}

Hierarchical clustering groups similar objects into a dendrogram. It merges similar clusters iteratively, starting with each data point as a separate cluster. This creates a tree-like structure that shows the relationships between clusters and their hierarchy. We are essentially building a hierarchy of clusters.
