title: What is the relation between J48 algorithm and decisionStump algorithm on weka?
body: <p>I have the test results on Weka and in the some of data sets there is not much difference between them when using J48 and decisionStump as an algorithm.</p>
  
  <p>How could J48 algorithm have no statistically significant difference to DecisionStump algorithm when comparing by accuracy (percent correct)? Can we find the relation by examining algorithms or structure of data?</p>
