Hi Spikey, thanks for the image. May I know what are the 4 lines referring to? I would guess the left side is input, right side is output? Why the 0.9 would change to 0.8 tho on the second picture? Also, if I am not taking it wrong, the third map range means that all the input that is lower than 0.9 will have an output to 0. So does the green line mean any linear relationships or are they simply arrows?
