abstract = {The radiation pattern within high energy quark- and
gluon-initiated jets (jet substructure) is used extensively
as a precision probe of the strong force as well as an
environment for optimizing event generators with numerous
applications in high energy particle and nuclear physics.
Looking at electron-proton collisions is of particular
interest as many of the complications present at hadron
colliders are absent. A detailed study of modern jet
substructure observables, jet angularities, in
electron-proton collisions is presented using data recorded
using the H1 detector at HERA. The measurement is unbinned
and multi-dimensional, using machine learning to correct for
detector effects. All of the available reconstructed object
information of the respective jets is interpreted by a graph
neural network, achieving superior precision on a selected
set of jet angularities. Training these networks was enabled
by the use of a large number of GPUs in the Perlmutter
supercomputer at Berkeley Lab. The particle jets are
reconstructed in the laboratory frame, using the
$k_{\mathrm{T}}$ jet clustering algorithm. Results are
reported at high transverse momentum transfer $Q^2>150$
GeV${}^2$, and inelasticity $0.2 < y < 0.7$. The analysis is
also performed in sub-regions of $Q^2$, thus probing scale
dependencies of the substructure variables. The data are
compared with a variety of predictions and point towards
possible improvements of such models.},
