Title:
ESTIMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/166564
Kind Code:
A1
Abstract:
An estimation device 400 has: an acquisition unit 421 that acquires a plurality of inference results that are respectively inferred as a result of inputting, to a learning model, multiple pieces of candidate data created on the basis of information indicating an unknown attribute candidate; a calculation unit 422 that for each inference result calculates the distance between the inference result acquired by the acquisition unit 421 and a label corresponding to the candidate data; and an estimation unit 423 that estimates an unknown attribute value in accordance with the result calculated by the calculation unit 422.
