Hello,
I'm experimenting with k-means clustering. When using certain values for k,
silhouette score returns NaN. Is that a bug or is that how it's supposed to
work? What does it mean? If it is not a bug, I think the function should return
something more meaningful when it fails.
PS: I have sent this message before registering, so it got blocked. I looked at
the list archive and I couldn't find it. So I think it never made to the list,
so I'm resending it. If you received this message two times, I'm sorry :(
