  In this contribution, a measurement of the top quark pole mass
$m_{\text{t}}^{\text{pole}}$ is presented. Events where a top quark-antiquark
pair ($\text{t}\bar{\text{t}}$) is produced in association with at least one
additional energetic jet ($\text{t}\bar{\text{t}}$+jet) are analyzed. The data
set recorded by the CMS experiment at a center-of-mass energy of 13 TeV,
corresponding to a total integrated luminosity of 36.3fb$^{-1}$, is used.
Reconstructed events are required to contain two opposite-sign leptons in the
final state. Machine learning methods are employed for the reconstruction of
the main observable event classification. The normalized
$\text{t}\bar{\text{t}}$+jet production cross section as a function of the
inverse of the invariant mass of the $\text{t}\bar{\text{t}}$+jet system is
measured at the parton level using a likelihood unfolding method. The value for
$m_{\text{t}}^{\text{pole}}$ is extracted by comparing the measurement to
next-to-leading order theoretical predictions using two parton distribution
functions (PDFs). For a reference set of the ABMP16NLO PDF, the resulting value
is $m_{\text{t}}^{\text{pole}} = 172.94\pm1.37$ GeV.
