agglomerative clustering example distance matrix
Hierarchical Clustering
Most popular hierarchical clustering technique • Basic algorithm 1 Compute the distance matrix between the input data |
For most common hierarchical clustering software, the default distance measure is the Euclidean distance.
This is the square root of the sum of the square differences.
However, for gene expression, correlation distance is often used.
What is distance matrix in clustering?
A distance matrix is a table that shows the distance between pairs of objects.
For example, in the table below we can see a distance of 16 between A and B, of 47 between A and C, and so on.
By definition, an object's distance from itself, which is shown in the main diagonal of the table, is 0.
Is agglomerative clustering distance based?
Agglomerative clustering can be used as long as we have pairwise distances between any two objects.
The mathematical representation of the objects is irrelevant when the pairwise distances are given.
