title: weka J48 feature selection
body: <p>I am using Weka and applying J48 to build my classifier. I have 40 features with 2000 instances (700 class a and 1300 class b).</p>
  
  <p>The J48 decision tree is just using 2 features out of 40! Is there anyway to allow J48 to use all features or is there any other algorithm that allows using all features?</p>
  
  <p>Thanks in advance.</p>
