title: Weka normalizing columns
body: <p>I have an ARFF file containing 14 numerical columns. I want to perform a normalization on each column separately, that is modifying the values from each colum to (<code>actual_value - min(this_column)) / (max(this_column) - min(this_column)</code>). Hence, all values from a column will be in the range <code>[0, 1]</code>. The min and max values from a column might differ from those of another column.</p>
  
  <p>How can I do this with Weka filters? </p>
  
  <p>Thanks</p>
