Abstract
An information processing apparatus () acquires a feature vector () obtained based on signal data () of a detected value of a sensor () that senses gas to be measured. The information processing apparatus () decomposes the feature vector () into a product of a coefficient vector and a feature matrix by using a non-negative matrix factorization (NMF). The detected value of the sensor () changes according to an attachment and a detachment of a molecule contained in a sensed gas. A value of each element of the feature vector () is equal to or greater than zero.
