<p>I have been reading on cross validation and wanted to experiment with Apache Spark's Mllib. I tried to read the provided material (<a href="https://spark.apache.org/docs/1.2.1/ml-guide.html" rel="nofollow">link</a>) but it is still very unintuitive and unclear to me how it works when using <code>LogisticRegressionWithLBFGS</code> classifier. </p>

<p>I would say I have a conceptual understanding of the cross validation topic and would need a little more help in understanding. I was wondering where the correct space is to ask. </p>
