移動推定装置、移動推定方法、及び移動推定プログラム

Japanese Patent JP7231052

B2

An object is to make it possible to accurately estimate the number of movements at a high speed. A generation unit (130) generates an optimization problem for estimating, with respect to each of a plurality of areas, the number of observation targets that move from the area to each of the other areas at each observation time point, as the number of movements, based on observation values and movement probabilities, the observation values indicating, with respect to each area, the number of observation targets that are present in the area at each observation time point, and the movement probabilities indicating, with respect to each area, probabilities of movement from the area to the other areas at each observation time point. A first estimation unit (140) estimates the number of movements by solving the generated optimization problem using a Sinkhorn-Knopp algorithm. A second estimation unit (160) estimates the movement probabilities based on the observation values and the estimated number of movements. An estimation control unit (120) repeats generation of the optimization problem, estimation of the number of movements, and estimation of the movement probabilities until a condition determined in advance is satisfied.
