I committed and pushed some not-finished yet code... so you could
torture if you like, but first I want to bring your attention to the
following misfunction imho:
In [27]:AUCErrorFx()([0.5, 0.5], [0, 1])
Out[27]:1.0
In [28]:AUCErrorFx()([0.5, 0.5, 0.5, 0.5], [0, 1, 0, 1])
Out[28]:0.75
In [29]:AUCErrorFx()([0.5, 0.5, 0.5, 0.5, 0.5, 0.5], [0, 1, 0, 1, 0, 1])
Out[29]:0.666666666667
shouldn't in all of those cases we get 0.5?
I know that it is a boundary and artificial case, but!
So whoever is awake, he is welcome to join the coding ;)
