title: How to suppress stdout for Stanford NLP ColumnDataClassifier.makeClassifier() function
body: <p>I am making a call to <code>edu.stanford.nlp.classify.ColumnDataClassifier.makeClassifier()</code>, and I need to block the std out that it generates. I tried setting <code>displayedColumn=-1</code> in the .prop file, but it does not see to me help. The following is the console output <code>makeClassifier()</code> generates that I want to eliminate. Can someone help?</p>
  
  <p>Console output:</p>
  
  <pre><code>QNMinimizer called on double function of 1596 variables, using M = 15.
                 An explanation of the output:
  Iter           The number of iterations
  evals          The number of function evaluations
  SCALING        &lt;D&gt; Diagonal scaling was used; &lt;I&gt; Scaled Identity
  LINESEARCH     [## M steplength]  Minpack linesearch
                     1-Function value was too high
                     2-Value ok, gradient positive, positive curvature
                     3-Value ok, gradient negative, positive curvature
                     4-Value ok, gradient negative, negative curvature
                 [.. B]  Backtracking
  VALUE          The current function value
  TIME           Total elapsed time
  |GNORM|        The current norm of the gradient
  {RELNORM}      The ratio of the current to initial gradient norms
  AVEIMPROVE     The average improvement / current value
  EVALSCORE      The last available eval score
