Hi,
I am using the PAM and CLARA packages in R and have found that the =
resulting clusters do not vary between runs. As I understand, these =
algorithms should both have random starting points and, therefore, their =
solutions should vary from run to run (unless the clustering is =
trivial). This is the case with K-means on the dataset that I am using. =
Could anyone explain why this might be occurring.
Thanks,
Allan.
