Good Day, I have to determine the number of cluster that I must have for a base of 578 records with 38 variables, someone can indicate me which would be the procedure in KNIME that I must continue, bearing in mind that is the first time that I am going to realize it. Thank you.

Hi Julio, 

That is a big question, and probably not one that we are likely to be able to answer here on the KNIME Forums.  For an introduction to unsupervised learning and other topics in Machine Learning, I would suggest having a look at the coursera course from Andrew Ng, linked below.
