A global Bayesian analysis of relativistic Pb + collisions at $\sqrt{s}_{\rm NN}$ = 2.76 TeV is performed, using a multistage model consisting an IP-Glasma initial state, viscous fluid dynamical evolution, and hadronic transport final state. The observables considered are from the soft sector Posterior Maximum Posteriori parameter distributions that pertain to hydrodynamic phases obtained, including shear bulk specific viscosity strong interacting matter. first use inference with transfer learning in heavy-ion analyses presented, together Bayes Model Averaging.
