Hi
Let assume that we have two clusters of points(n-dimension)- How one can find the distance between those two clusters?
There are different approaches for that
Single Linkage: defines the distance between two clusters c1 and c2 as the minimal distance between any two points x, y with x in c1 and y in c2.
Complete Linkage: defines the distance between two clusters c1 and c2 as the maximal distance between any two points x, y with x in c1 and y in c2.
Average Linkage: defines the distance between two clusters c1 and c2 as the mean distance between all points in c1 and c2.
could you please clarify your question? Are you interested in calculating these cluster distances in KNIME? Or do you want to know which of the mentioned options to choose?
I created a workflow calculating the distances. As one needs to calculate all distance pairs between all data points, this can be pretty resource hungry if you input a large dataset.
