Cannot change k-value for the sample kmean with plot.
hello community. I need to do k-means cluster using rapidminer and produce elbow method graph. i've tested the k-means clustering with plot sample. However, when I try to change the k value from 13 to 5 for the k-means operator and run, the k value does not change instead it turn back to 13 and produce 13 cluster. Can someone tell me what is the problem and solution?
Thank you in advance.
