Inspired by the research on detecting the steerability of two-qubit states via machine learning,this study explores the detection of steerability in qubit-qutrit systems using various machine learning methods.It is found that,(1)for random states,Werner states,and UN states(a newly constructed class of entangled states where Alice cannot steer Bob),there always exist supervised or semi-supervised machine learning methods with a steering detectability accuracy rate of over 95％;(2)the steering bounds predicted by the supervised machine learning methods are mostly higher than the non-steerable bounds provided by theory and lower than the steering bounds determined by the semidefinite programming(SDP).This demonstrates that the machine learning methods are reliable for detecting the steerability of quantum states in qubit-qutrit systems and can detect more steering states compared with the SDP method.It lays the foundation for utilizing machine learning methods to detect quantum states'steerability in bipartite and high-dimensional systems.
