Abstract
An information processing apparatus () acquires time-series data () output by a sensor () and computes a plurality of feature constants θand a contribution value ξrepresenting contribution with respect to the time-series data () for each feature constant θ. Thereafter, the information processing apparatus () outputs information in which a set Θ of the feature constants θand a set Ξ of the contribution values ξare associated with each other as a feature value of a target gas. As the feature constant θ, a velocity constant β or a time constant τ that is a reciprocal of the velocity constant can be adopted.
