LEARNING DEVICE, INFERENCE DEVICE, LEARNING METHOD, INFERENCE METHOD, AND LEARNING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/014541
Kind Code:
A1
Abstract:
In this learning device, a neural network: receives, as inputs, low-resolution data that is low in resolution and that represents demographics including locations and densities, first supplemental information that relates to the types of places in areas and the locations of the places, and second supplemental information that represents time, weather, and/or other information representing time-series change; and outputs enhanced-resolution data obtained by enhancing the resolution of the demographics. The learning device: obtains enhanced-resolution intermediate data by enhancing the resolution of learning low-resolution data for each combination of an area and a time period; obtains, for each combination of an area and a time period, a weight for a type of place using the first supplemental information for the type of place and the second supplemental information; outputs enhanced-resolution data obtained by integrating weighted first supplemental information for each type of place with the enhanced-resolution intermediate data; and learns the parameters of the neural network on the basis of the enhanced-resolution data, which is output from the neural network, and on the basis of learning high-resolution data for each combination of an area and a time period.
