abstract = {We apply adversarial domain adaptation in unsupervised
setting to reduce sample bias in a supervised high energy
physics events classifier training. We make use of a neural
network containing event and domain classifier with a
gradient reversal layer to simultaneously enable signal
versus background events classification on the one hand,
while on the other hand minimizing the difference in
response of the network to background samples originating
from different Monte Carlo models via adversarial domain
classification loss. We show the successful bias removal on
the example of simulated events at the Large Hadron Collider
with $t\bar{t}H$ signal versus $t\bar{t}b\bar{b}$ background
classification and discuss implications and limitations of
the method.},
