Unit space updating apparatus, unit space updating method and program

摘要

This unit space updating device (20) which generates a unit space comprises: a detected value acquisition unit (211) that acquires a bundle of detected values detected in a constant cycle; and a deletion processing unit (213) that deletes a bundle from the plurality of bundles of the detected values configuring the unit space when the bundle of the detected values is added to the unit space. The deletion processing unit (213) includes at least one of: a first processing unit (213A) that randomly deletes a bundle from the plurality of bundles of the detected values that configure the unit space; and a second processing unit (213B) which, with respect to the detected value of the predetermined judgment criterion, among the plurality of judgment criteria, any bundle among bundles containing the detected values with the highest frequency of occurrence in the unit space, or one of two bundles with the the smallest difference between the detected values in the unit space.
