Area under the \(Min(FPR, FNR)\) (AUM) — nnf_area_under_min_fpr_fnr • torch

Function that measures Area under the $M i n (F P R, F N R)$ (AUM) between each element in the $i n p u t$ and $t a r g e t$ .

Usage

nnf_area_under_min_fpr_fnr(input, target)

Arguments

input: Tensor of arbitrary shape
target: Tensor of the same shape as input. Should be the factor level of the binary outcome, i.e. with values 1L and 2L.

Details

This is used for measuring the error of a binary reconstruction within highly unbalanced dataset, where the goal is optimizing the ROC curve.
