So I use kmeans to 10k data with k = 8 as I took it from elbow analysis that will suggest me 5-8 cluster
After the analysis, I got 1 cluster that only consist 1 member in it which I was not sure how I will see any pattern in it.
What should I do to that cluster? Should I ignore it (as elbow shows me that 7 cluster is ok) and go on with other 7?
Notes: I have tried all k from k=5 to 8 and validate it using silhouette coefficient. the results are not so far between each k.
