abstract = {he increasing use of machine learning approaches on
neuroimaging data comes with the important concern of
confounding variables which might lead to biased predictions
and in turn spurious conclusions about the relationship
between the features and the target. A prominent example is
the brain size difference between women and men. This
difference in total intracranial volume (TIV) can cause bias
when employing machine learning approaches for the
investigation of sex differences in brain morphology. A
TIV-biased model will not capture qualitative sex
differences in brain organization but rather learn to
classify an individual’s sex based on brain size
differences, thus leading to spurious and misleading
conclusions, for example when comparing brain morphology
between cisgender- and transgender individuals. In this
study, TIV bias in sex classification models applied to cis-
and transgender individuals was systematically investigated
by controlling for TIV either through featurewise confound
removal or by matching the training samples for TIV. Our
results provide strong evidence that models not biased by
TIV can classify the sex of both cis- and transgender
individuals with high accuracy, highlighting the importance
of appropriate modeling to avoid bias in automated decision
making.},
