Title:
ESTIMATION DEVICE, ESTIMATION METHOD, PROGRAM, AND LEARNED MODEL GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/124992
Kind Code:
A1
Abstract:
According to the present invention, deformation of a member is estimated without directly measuring the deformation. An estimation device (1) for estimating an unknown target physical quantity among at least three physical quantities that change in accordance with deformation in a member (2) that linearly or non-linearly deforms, the target physical quantity being estimated from two other physical quantities among the at least three physical quantities by using a learned model (51) that is learned in advance. In the learned model (51), a plurality of the at least three physical quantities (3, 4, 6) including a target physical quantity (6) with which time-series information has been associated are learned using learning data. The learning is carried out so that at least two physical quantities (3, 4) other than the target physical quantity are used as inputs, and so that the target physical quantity (6) is outputted.
