Abstract
In order to appropriately extract feature quantities for use in machine learning or estimation of a stress level, an information processing apparatus (1, 4) includes: an identification means (11, 404) of identifying, as a time zone of interest, a time zone in which a chronic stress tendency is notably shown in biological signals which have been acquired from a subject over a predetermined time period; and an extraction means (12, 405) of extracting one or more feature quantities from biological signals acquired in the time zone of interest which has been identified, the one or more feature quantities being used in machine learning of an estimation model for estimating a stress level or used in estimation of a stress level using the estimation model.
