To decode "swtyblz", let's try a common substitution cipher technique.
decode swtyblz as = pretty boy
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 To decode "swtyblz", let's try a common substitution
Hmmm...
