GNS Causal Inference & Simulation

Discover New Knowledge with REFS™

The patented GNS REFS technology is the first commercially available causal machine learning and simulation platform that automates the transformation of diverse streams of biomedical and healthcare data into mechanistic, computer models that are representative of individual patients. Healthcare interventions – drugs, medical procedures, care management programs, medical devices, etc. – are simulated in these causal models to reveal the optimal health interventions, patient by patient, instead of the “one size fits all” approach of our current standard of care.
