Google Research presents five partner-driven case studies using the Population Dynamics Foundation Model (PDFM) as a proof-of-concept for planetary geospatial foundation models in public health.
PDFM embeddings, which compress privacy-preserving search trends, mobility, built-environment density, and environmental determinants, matched or improved on conventional inputs across tasks including MMR vaccination extrapolation, cardiovascular mortality nowcasting, dengue forecasting, postpartum depression risk prediction, and cholera outbreak prediction.
The model requires no task-specific fine-tuning and is refreshed at a monthly cadence.
