Fluctuating thermal fields in antiferromagnets are seen as a potential means to realize a probabilistic distribution in an output signal that can also be tailored by electrical control. To this end, the dynamics of a 90-degree domain wall driven by spin-orbit torque are theoretically examined in an antiferromagnetic structure at finite temperatures. The calculations clearly illustrate that both the average displacement of the domain wall and its thermally induced dispersion can be electrically modulated, or ``trained'', by tuning the driving spin-orbit torque. This unusual functionality could provide a key component in probabilistic computing and machine learning.
