title: Choose the right classification algorithm. Linear or non-linear?
body: <p>I find this question a little tricky. Maybe someone knows an approach to answer this question. Imagine that you have a dataset(training data) which you don't know what it is about. Which features of training data would you look at in order to infer classification algorithm to classify this data? Can we say anything whether we should use a non-linear or linear classification algorithm?</p>
  
  <p>By the way, I am using WEKA to analyze the data.</p>
  
  <p>Any suggestions?
  Thank you.</p>
