abstract = {Sex differences in the brain have received a wide interest
in neuroscientific research. Insteadof task-based group
comparisons, the present study employed a machine-learning
(ML)-approach to examine whether the resting-state
functional connectivity of 12 meta-analyticallydefined
networks carries enough information to accurately predict
the sex of a person. It washypothesized that especially
emotion-related networks should classify well. Sex
classificationanalyses were conducted in the datasets of the
healthy brain network (HBN, n = 218) theRockland Sample of
the enhanced Nathan Kline Institute (eNKI, n = 574), the
HumanConnectome Project (HCP, n = 734) and the
1000BRAINS-dataset (n = 995). The MLalgorithmsLASSO, LSVM,
Ridge and RVM were used for this classification approach.
Theresults showed that the eNKI- and HCP-datasets as well as
the algorithms LASSO and Ridgereceived on average higher
classification accuracies than the other datasets and
algorithms.The networks of autobiographical and semantic
memory reached the highest accuracies of allnetworks. Taken
together, the results did not support the initial
hypothesis. Instead, theresults generally displayed a strong
dependency on the datasets and ML-algorithms.},
