For transferring information from sub-cohorts of patients where only limited information is available to sub-cohorts of patients with comprehensive longitudinal characterization, we leverage that some types of assessments are categorical per-se, and that for others there are medically meaningful categorical representations. Specifically, we will learn the much simpler joint distribution of the categorical data in a pre-training step, and subsequently train a model again at the level of the quantitative measurements. Such simpler distributions will also be used to formalize and incorporate medical expert knowledge.
