Please add a plot regarding the results without use_zero. Can all algorithms somehow work with nan values or des it break any of them?

I adapted the two that could not handle NaN's until now so they behave like if I would have not removed that use_zero flag.

While you're at it, can you change num_epochs for LSTM_Enc_Dec to something low like 5-15 or so? It makes the benchmark run forever, and I just can't imagine that many epochs bringing any benefit.
