New DMF framework reconstructs physical systems from sparse measurements

Researchers have introduced Direct Measurement-to-Field Generation (DMF), a new framework designed to reconstruct physical systems from sparse, incomplete, or indirect measurements. This functional rectified flow approach learns to generate physical fields end-to-end by fusing local sensor data with global context, enabling accurate field evaluation at any query coordinate. DMF demonstrates superior performance over existing methods in benchmarks involving unobserved boundaries, missing training fields, and unmeasured quantities, while also providing reliable uncertainty quantification.
