Abstract: Provided is a learning device that includes an input unit configured to input training input data, training determination data for indicating a determination result with respect to the training input data, and training ground data for indicating a ground for the determination result with respect to the training input data; a determination learning unit, by performing first machine learning that learns a relationship between the training input data and the training determination data, configured to generate a determination inference model that, upon being inputted with input data, outputs inferred determination data; and a ground learning unit, by performing second machine learning that learns a relationship between the training input data and the training ground data, configured to generate a ground inference model that, upon being inputted with the input data, outputs inferred ground data.

Abstract: A physical quantity data correcting device accurately and rapidly makes corrections of physical quantity data by appropriately controlling an approximate ellipsoid computing unit and/or a correction coefficient computing unit on the basis of a control parameter group. A physical quantity data acquiring unit acquires physical quantity data output from a physical quantity detecting unit that detects physical quantities. A data selecting unit selects the acquired physical quantity data. An approximate ellipsoid computing unit computes an approximate expression of an n-dimensional ellipsoid indicating a distribution shape obtained by distributing the selected physical quantity data in an n-axis coordinate space. A correction coefficient computing unit computes correction coefficients for correcting the computed n-dimensional ellipsoid to an n-dimensional sphere.

Abstract: A physical quantity measuring apparatus of the present invention measures a physical quantity from a signal based on a physical quantity output by a physical quantity signal output apparatus. A correction signal output unit outputs a new correction signal based on a signal on the basis of a physical quantity obtained at a given measurement time, a correction signal obtained before that measurement time, and a filter coefficient. A large/small relationship determining unit determines a large/small relationship between the signal on the basis of the physical quantity and the correction signal obtained before that measurement time. A first filter coefficient output unit outputs a first filter coefficient based on the plural large/small relationships.
