hclust count number of merges & first merge height for anomaly detection
I am using hclust function from R for hierarchical clustering. I am planning to use it for anomaly detection.
For detecting anomalies, I need a function that counts the merges that need to be done from leaf to the root.
Based on the image linked I need a function f1(x) that gives
f1(3) = 2
f1(7) = f1(6) = 3
f1(2) = 4
Following a similar desire to detect anomalies, I also need another function f2(x) to find the first merging hight for individual leaves. For the same picture given
f2(3) ~ 0.7
f2(7) ~ 0.35 etc.
Thank you
