title: Cross Validation in Scikit Learn
body: <p>I have been using <a href="http://scikit-learn.org/stable/modules/generated/sklearn.cross_validation.cross_val_score.html" rel="nofollow">http://scikit-learn.org/stable/modules/generated/sklearn.cross_validation.cross_val_score.html</a></p>
  
  <p>in order to cross validate a Logistic Regression classifier. The results I got are:</p>
  
  <pre><code>[ 0.78571429  0.64285714  0.85714286  0.71428571  
  0.78571429  0.64285714    0.84615385  0.53846154  
  0.76923077  0.66666667]
  </code></pre>
  
  <p>My primary question is how I could find which set/fold maximises my classifier's score and produces 0.857.</p>
  
  <p>Follow-up question: Is training my classifier with this set a good practice?</p>
  
  <p>Thank you in advance.</p>
