Abstract: A measurement apparatus includes a signal sensor unit configured to measure a measurement signal in which a target signal and first noise are mixed and detect a first noise signal of which a level of a component of the target signal is lower than a predetermined value and which includes the first noise, and include one or more signal sensors; and a processing unit performing processing of reducing a component of the first noise included in measurement data by data partitioned factor analysis on the basis of the measurement data that is data of the measurement signal measured by the signal sensor unit and control data that is data of the first noise signal measured by the signal sensor unit.

Abstract: Provided is an information processing device capable of improving the accuracy of removing noise from a result of measuring a desired signal when a plurality of reference sensors are used. An information processing device includes an acquisition unit configured to acquire signal measurement results of one or more signal sensors for measuring a mixed signal in which an objective signal and noise are mixed and noise measurement results of a plurality of reference sensors for measuring the noise and a signal processing unit configured to divide the signal measurement results and the noise measurement results acquired by the acquisition unit into a plurality of frequency bands for each of a plurality of division segments in a time domain and perform signal processing for removing the noise included in the mixed signal.
