Learning device, learning method, and learning program

Abstract

Obtain stable positioning results. [Solution] The learning device (2) includes a teacher data acquisition unit (203) that acquires teacher data (212) to which the floor level of each point and whether or not the point is an open-plan area are associated as correct labels with the difference between the atmospheric pressure measured at each point inside the building and the atmospheric pressure measured at a predetermined reference point, and a learning unit (204) that generates an estimation model (112) for estimating the floor level of the measurement point and whether or not the measurement point is an open-plan area from the atmospheric pressure difference between the measurement point and the reference point by learning using the teacher data (212).

Claims

1. A training data acquisition unit acquires training data in which the difference between the atmospheric pressure measured at each point inside the building and the atmospheric pressure measured at a predetermined reference point is associated with the floor level of each point and whether or not that point is in an open area as correct labels. A learning device comprising: a learning unit that generates an estimation model for estimating the hierarchical level of a measurement point and whether or not the measurement point is an open area, based on the pressure difference between the measurement point and a reference point, by learning using the aforementioned training data.

2. The aforementioned training data includes data showing the received signal strength of LPWA measured at various points within the building.
