abstract = {Noninvasive brain stimulation can reduce severity of
tinnitus phantom sounds beyond time of stimulation by
inducing regional neuroplastic changes. However, there are
no good clinical predictors for treatment outcome. We used
machine learning to investigate whether brain anatomy can
predict therapeutic outcome. Sixty-one chronic tinnitus
patients received repetitive transcranial magnetic
stimulation of left dorsolateral prefrontal and temporal
cortex. Before repetitive transcranial magnetic stimulation,
a structural magnetic resonance image was obtained from all
patients. To predict individual treatment response in new
subjects, we employed a support-vector machine ensemble for
individual out-of-sample prediction. In the
cross-validation, the support-vector machine ensemble based
on stratified subsampling and feature selection yielded an
area under the curve of 0.87 for prediction of therapy
success in new, previously unseen subjects. This
corresponded to a balanced accuracy of $83.5\%,$ sensitivity
of $77.2\%,$ and specificity of $87.2\%.$ Investigating the
most selected features showed the involvement of auditory
cortex but also revealed a network of nonauditory brain
areas. These findings suggest that idiosyncratic brain
patterns accurately predict individual responses to
repetitive transcranial magnetic stimulation treatment for
tinnitus. Our findings may hence pave the way for future
investigations into precision treatment of tinnitus,
involving automatic identification of the appropriate
treatment method for the individual patient.},
