I performed K-means on a data-set. I have a question about some parameters that I got.
Sepal.Length Sepal.Width Petal.Length Petal.Width
1 5.006000 3.428000 1.462000 0.246000
In this case, what does “Cluster means” stands for?
I also get the following:
between_SS/total_SS = 90%
How can this value be interpreted?
