PROBLEM TO BE SOLVED: To detect target data in a shorter time.SOLUTION: A detection program causes a computer to executes the following processing: executing a plurality of change-point detection processes for detecting change points of time-series data to be evaluated, at multiple granularity levels different in width of unit time; storing a first detection pattern indicating a change-point detection process corresponding to each of the detected change points, in a storage section; detecting change points of new time-series data to be evaluated, at different granularity levels; and outputting different information, according to whether the first detection pattern stored in the storage section coincides with a second detection pattern indicating a change-point detection process corresponding to each of the change points of the new time-series data.SELECTED DRAWING: Figure 1 |
