Claim One:
1. A time series data dimensional compression apparatus, comprising: (1) a time series data generating section that generates a plurality of pieces of time series data of a specified length by sliding a start point of time series data at a predetermined interval along a time axis on time series source data that is sequential data measured at a regular interval along the time axis; (2) a time series subsequence generating section that generates time series subsequences of a specified segment width by which each of the plurality of pieces of time series data is divided; (3) a singular value decomposition processing section that performs singular value decomposition on all of the divided time series subsequences; and (4) a dimensional compression time series data generating section that generates dimensional compression time series data by using a specified number of high-order elements of the singular value decomposition as a representative value of each of the divided time series subsequences of the specified segment width.
