Abstract: A machine learning method for model-free inference of target physical parameters from a metrology dataset is generally disclosed. The disclosed method is particularly applied to atomic interferometry for sensing/measuring physical quantities such as acceleration and rotations from measured atomic interference patterns. The method operates without a need for an exact measurement-dependent mathematical/analytical model and without a need for explicit knowledge of instrumental error processes that affect the measurement. The disclosed method is based on neural networks that are trained or calibrated to learn to simultaneously estimate the target physical quantities of interest and their measurement uncertainties. It extends the applicability of a metrology when instrumental precision is limited, and noise and imperfections are present.
