title: How to make Doc2Vec document vectors all positive?
body: <p>I'm trying to use nonnegative matrix factorization on the output of Doc2Vec. However there is a constraint that there can be no negative input. How do I make it positive without doing something like absolute value that will construe the results? If it helps, I'm loading in a new paragraph and computing similarity but I thought that using Doc2Vec would capture more meaning.</p>
