Title:
POPULATION STATE DETERMINATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/024201
Kind Code:
A1
Abstract:
The present invention suitably determines the state of a population. A population state determination system 10 comprises: an acquisition unit 11 that acquires population information indicating a population in a time series for an area in which the state of the population is to be determined; a model calculation unit 12 that inputs the population information acquired by the acquisition unit 11 into an encoder-decoder model, which is stored in advance and which compresses and restores input data, and that performs a calculation, obtaining an output from the encoder-decoder model; a determination unit 13 that compares the population information acquired by the acquisition unit 11 and the output obtained by the model calculation unit 12 and determines the state of the population in the area; and a determination criteria generation unit 14 that generates determination criteria used for determination by the determination unit 13. The determination criteria generation unit 14 generates the determination criteria by inputting population information for determination criteria generation to an encoder-decoder model for determination criteria generation that is stored in advance and then performing calculation.
