title: Why no word embeddings (Glove, word2vecetc) used in first attention paper?
body: <p>In the paper <a href="https://arxiv.org/abs/1409.0473" rel="nofollow noreferrer">Neural Machine Translation by Jointly Learning to Align and Translate Bahdanau et. al.</a> why are there no word embeddings such as Glove or word2vec used? </p>
  
  <p>I understand that this was a 2014 paper, but the current implementations of the paper on github don't use any word embeddings as well?</p>
  
  <p>For trying to code the paper is using word embeddings reasonable?</p>
