title: What does RepeatedKFold actually mean?
body: <p>Say <code>n_repeats=5</code> and the number of fold is 3 (<code>n_splits=3</code>).</p>
  
  <p>Does that mean the validator is creating 3-folds for our estimator/model to use every fold (like what KFold is for), then repeating that process for 5 times?</p>
  
  <p>That means our model will use a total of 5 x 3 = 15 folds?</p>
