Web8 dec. 2024 · Usually, the AUC is in the range [0.5, 1] because useful classifiers should perform better than random. In principle, however, the AUC can also be smaller than 0.5, which indicates that a classifier performs worse than a random classifier. WebWe can roughly motivate the factor of 2 difference by noting that if you subtract off the lower large diagonal line (which makes the top line approximately horizontal as well, at this order), then the curve is more or less a parabola whose vertex is the midpoint - and it's a standard fact that over an interval that's symmetric about and tangent …
