Abstract
An odor identification method includes: obtaining a plurality of detection signals output from a plurality of sensors exposed to a sample gas; determining, for each of the plurality of sensors, whether the sensor is anomalous based on a feature extracted from the signal output from the sensor; selecting one of a plurality of trained logical models that are for identifying an odorant and different from each other, based on a result of determination in the determining; and identifying the odorant contained in the sample gas, based on the plurality of detection signals obtained in the obtaining of the plurality of detection signals and the one of the plurality of trained logical models selected in the selecting.
Claims9
An odor identification method of identifying an odorant contained in a sample gas, using a plurality of sensors each outputting a signal according to an adsorption concentration of molecules, the odor identification method comprising:
- obtaining a plurality of detection signals output from the plurality of sensors exposed to the sample gas;
- determining, for each of the plurality of sensors, whether the sensor is anomalous based on a feature extracted from the signal output from the sensor;
- selecting one of a plurality of trained logical models that are for identifying the odorant and different from each other, based on a result of determination in the determining;
- and
- identifying the odorant contained in the sample gas, based on the plurality of detection signals obtained in the obtaining of the plurality of detection signals and the one of the plurality of trained logical models selected in the selecting.
An odor identification system for identifying an odorant contained in a sample gas, using a plurality of sensors each outputting a signal according to an adsorption concentration of molecules, the odor identification system comprising:
- an obtainer that obtains a plurality of detection signals output from the plurality of sensors exposed to the sample gas;
- a determiner that determines, for each of the plurality of sensors, whether the sensor is anomalous based on a feature extracted from the signal output from the sensor;
- a selector that selects one of a plurality of trained logical models that are for identifying the odorant and different from each other, based on a result of determination by the determiner;
- and
- an identifier that identifies the odorant contained in the sample gas, based on the plurality of detection signals obtained by the obtainer, and the one of the plurality of trained logical models selected by the selector.
