Clustering Analysis


Can we do K means clustering using recency frequency monetary data?

How to do validation in clustering data set? If you have divided the dataset into two parts training and validation dataset…In training dataset , I have applied clustering analysis …How do I apply in validation dataset.


You have to always and only, ever apply any technique that you applied to your training data EXACTLY the same way to your test (validation) data. That is how you see how well it worked.


Unsupervised forced into a supervised learning? I am a little confused.
