title: How to treat numbers inside text strings when vectorizing words?
body: <p>If I have a text string to be vectorized, how should I handle numbers inside it? Or if I feed a Neural Network with numbers and words, how can I keep the numbers as numbers? </p>
  
  <p>I am planning on making a dictionary of all my words (<a href="https://github.com/tflearn/tflearn/issues/124#issuecomment-223478145" rel="noreferrer">as suggested here</a>). In this case all strings will become arrays of numbers. How should I handle characters that are numbers? how to output a vector that does not mix the word index with the number character?</p>
  
  <p>Does converting numbers to strings weakens the information i feed the network?</p>
