D Loss Interpretation

[ghost]

Thank you for sharing the code.

Say if,
D should maximise D(f)-D(r) , => minimising D(r)- D(f)
and G should minimise D(f)-D(r) => minimising D(f).

And your code also follows the same logic. But I'm unable to comprehend from D loss curve, why is the loss increasing from ( -15 to around zero). Shouldn't the curve go down as iterations happen, since we are minimising the loss( D(r)-D(f)?
