We consider the specific setup where the distribution of the system's trajectories is unknown but the following two sources of information are available: \\textit{(i)} some \"rough\" prior knowledge on the system's realisations; \\textit{(ii)} a set of \"incomplete\" observations of the system's trajectories. We propose a Bayesian methodological framework to build reduced-order models (ROMs) by exploiting these two sources of information.
