title: How to choose a Feature Selection Algorithm? - advice
body: <p>Is there a research paper/book that I can read which can tell me for the problem at hand what sort of feature selection algorithm would work best. </p>
  
  <p>I am trying to simply identify twitter messages as pos/neg (to begin with). I started out with Frequency based feature selection (having started with NLTK book) but soon realised that for a similar problem various individuals have choosen different algorithms</p>
  
  <p>Although I can try Frequency based, mutual information, information gain and various other algorithms the list seems endless.. and was wondering if there an efficient way then trial and error. </p>
  
  <p>any advice</p>
