abstract = {Goal: Machine learning (ML) technologies that leverage
large-scale patient data are promising tools
predictingdisease evolution in individual patients. However,
the limited generalizability of ML models developed on
single-center datasets,and their unproven performance in
real-world settings, remain significant constraints to their
widespread adoption in clinicalpractice. One approach to
tackle this issue is to base learning on large multi-center
datasets. However, such heterogeneous datasetscan introduce
further biases driven by data origin, as data structures and
patient cohorts may differ between hospitals. Methods:
Inthis paper, we demonstrate how mechanistic virtual patient
(VP) modeling can be used to capture specific features of
patients’states and dynamics, while reducing biases
introduced by heterogeneous datasets. We show how VP
modeling can be used for dataaugmentation through
identification of individualized model parameters
approximating disease states of patients with suspectedacute
respiratory distress syndrome (ARDS) from observational data
of mixed origin. We compare the results of an
unsupervisedlearning method (clustering) in two cases: where
the learning is based on original patient data and on data
derived in the matchingprocedure of the VP model to real
patient data. Results: More robust cluster configurations
were observed in clustering using themodel-derived data. VP
model-based clustering also reduced biases introduced by the
inclusion of data from different hospitalsand was able to
discover an additional cluster with significant ARDS
enrichment. Conclusions: Our results indicate
thatmechanistic VP modeling can be used to significantly
reduce biases introduced by learning from heterogeneous
datasets and toallow improved discovery of patient cohorts
driven exclusively by medical conditions.},
