title: How to find the closest word to a vector using word2vec
body: <p>I have just started using Word2vec and I was wondering how can we find the closest word to a vector suppose.
   I have this vector which is the average vector for a set of vectors:</p>
  
  <pre><code>array([-0.00449447, -0.00310097, 0.02421786, ...], dtype=float32)
  </code></pre>
  
  <p>Is there a straight forward way to find the most similar word in my training data to this vector?</p>
  
  <p>Or the only solution is to calculate the cosine similarity between this vector and the vectors of each word in my training data, then select the closest one?</p>
  
  <p>Thanks.</p>
