Abstract: A gas identification method uses a sensor for outputting a signal corresponding to an adsorption concentration of a gas, and includes: acquiring a signal output from the sensor that is exposed to a sample gas only during a second period out of a measurement period including a first period, the second period following the first period, and a third period following the second period; extracting one or more feature quantities corresponding to the drift of the signal acquired; and, identifying the sample gas based on the one or more feature quantities extracted, using a learned logical model for identifying the sample gas, and outputting an identification result.
