Inflationary segment approach to temporal data partitioning for optimized model scoring

Abstract:

A method for segmenting a data series, including the steps of: receiving a data series comprising a plurality of change points; analyzing, by a processor, the received data series sequentially, comprising the steps of: (i) identifying a first change point in the data series; (ii) automatically assigning the identified first change point as a starting point for a first data segment; (iii) identifying, using only the data in the first data segment, a second change point in the data series; and (iv) automatically assigning the identified second change point as a starting point for a second data segment; and storing, in a database, the first and second identified change points, and the first and second data segments.
