A control apparatus () includes a signal detection unit () and a data acquisition unit (). The signal detection unit () acquires operation signals relating to an operation of a processing apparatus () that processes food and drink, and detects a specific operation signal relating to a specific operation from among the operation signals. The data acquisition unit () determines, based on a detection timing of the specific operation signal, a data acquisition period of an odor sensor () provided in the processing apparatus (), and acquires output data being output from the odor sensor () during the data acquisition period.

Control apparatus, data acquisition method, and non-transitory computer-readable medium

In a noise removing apparatus, a data acquisition unit acquires sets of odor data measured using a sensor with respect to a plurality of objects, each set of odor data representing features of an odor of an object by respective rates of a plurality of odor molecules. A noise component extraction unit extract a noise component using a set of odor data. A noise removing unit removes the noise component from each set of odor data to be processed.

Noise removing apparatus, noise removing method, and recording medium

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.
