Hmmm...

Deep feature : a notion in machine learning referring to a feature that is computed using a complex algorithm, often a neural network, that transforms simple features into more abstract and useful representations. swtyblz encodes

Now if "swtyblz" encodes: give me a feature often a neural network

then

If I assume that each letter is shifted by a certain number of places, I can try to decode it. swtyblz encodes
