Abstract
A time-series data processing device (10) takes as input time-series data being a sequence of values sequentially obtained over time. The time-series data processing device (10) extracts, as an extension leg, subsequence data which is segmented from the time-series data and whose value increases or decreases over time. The time-series data processing device (10) identifies, from the extracted extension leg, an appearance pattern including an extension rising leg whose value increases over time and an extension falling leg whose value decreases over time.
Claims10
A time-series data processing device comprising:
- a leg extraction unit to take as input time-series data being a sequence of values sequentially obtained over time, and to extract, as an extension leg, subsequence data which is segmented from the time-series data and in which a value at a terminal point is higher or lower than a value at a start point;
- and
- an appearance pattern identification unit to identify, from the extension leg extracted by the leg extraction unit, a suite of extension legs where an extension rising leg in which a value at a terminal point is higher than a value at a start point, and an extension falling leg in which a value at a terminal point is lower than a value at a start point, appear in an order of a reference pattern.
A non-transitory computer-readable recording medium which records a time-series data processing program comprising:
- a leg extraction process of taking as input time-series data being a sequence of values sequentially obtained over time, and extracting, as an extension leg, subsequence data which is segmented from the time-series data and in which a value at a terminal point is higher or lower than a value at a start point;
- and
- an appearance pattern identification process of identifying, from the extension leg extracted by the leg extraction process, a suite of extension legs where an extension rising leg in which a value at a terminal point is higher than a value at a start point, and an extension falling leg in which a value at a terminal point is lower than a value at a start point, appear in an order of a reference pattern.
