While TensorFlow may be not yet as mature as Theano or Torch, I love their tutorial: <a href="https:&#x2F;&#x2F;www.tensorflow.org&#x2F;versions&#x2F;master&#x2F;tutorials&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.tensorflow.org&#x2F;versions&#x2F;master&#x2F;tutorials&#x2F;</a>. It&#x27;s clean, concrete, and more general than introduction to their API. (Before I couldn&#x27;t find anything comparable in Theano or Torch.)<p>In any case, I regret waiting so long for learning deep learning. (I thought that I needed to have many years of CUDA&#x2F;C++ knowledge (I have none); but in fact, what I need to to know the chain rule, convolutions etc - things I&#x27;ve learnt long time ago.)
