Title:
TRANSMITTING TERMINAL SPECIFYING DEVICE, TRANSMITTING TERMINAL SPECIFYING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/189122
Kind Code:
A1
Abstract:
[Problem] To provide a transmitting terminal specifying device capable of generating an identification model that is robust against environmental changes. [Solution] This transmitting terminal specifying device comprises: a reception unit, a feature quantity extraction unit, a first learning unit, a likelihood calculation unit, an analysis unit, and a label assigning unit. The reception unit receives a signal from a terminal. The feature quantity extraction unit extracts a feature quantity from the reception signal received by the reception unit. The first learning unit learns a first feature quantity in which a signal is known to be received from a terminal to be identified, and generates a first classifier for identifying the terminal to be identified. The likelihood calculation unit inputs, to the first classifier, a second feature quantity in which whether or not a signal is received from the terminal to be identified is unknown, and calculates a likelihood distribution representing the likelihood of each terminal. The analysis unit analyzes the likelihood distribution and determines whether or not a temporary label can be assigned to the second feature quantity. The label assigning unit assigns, on the basis of the result of the analysis unit, a temporary label to the second feature quantity.
