Does tensorflow use automatic or symbolic gradients?
<p>I haven't been able to find a clear statement of whether tensorflow uses automatic or symbolic differentiation.</p>

<p>I skimmed the tensorflow <a href="http://download.tensorflow.org/paper/whitepaper2015.pdf" rel="noreferrer">paper</a> and they mention automatic gradients, but it is unclear if they just mean symbolic gradients, as they also mention that it has that capability.</p>
