A new research paper proposes a method for causally falsifying digital twins, which are simulation models used to predict real-world processes. The authors frame the problem as a causal inference challenge, defining what it means for a twin to be accurate. They highlight that observational data alone cannot certify a twin without potentially unreliable assumptions. Instead, the proposed statistical procedure aims to identify situations where the twin is incorrect, even with confounded data, assuming an i.i.d. dataset of observational trajectories. The methodology was applied to a sepsis modeling case study using the Pulse Physiology Engine and the MIMIC-III dataset. AI
