Spark MLlib KMeansModel provides "computeCost" function which return the
sum of squared distances of points to their nearest center as the k-means
cost on the given dataset.

K-means Evaluation metrics

[janardhan shetty]

Hi,

I was trying to evaluate k-means clustering prediction since the exact
cluster numbers were provided before hand for each data point.
Just tried the Error = Predicted cluster number - Given number as brute
force method.

What are the evaluation metrics available in Spark for K-means clustering
validation to improve?
