Similarity Matching Algorithm of Multiple Granularities Time-Series Data

Focused on the present status that the algorithm of measuring time-series distance is many but the appropriate algorithm of measuring multiple granularities time-series is few, the paper advanced a similarity matching algorithm of multiple granularities time-series based on the ideal of time calibrator and hypothesis test. It firstly expounded the definition of multiple granularities time-series, furthermore proposed a sample of distance; secondly it put forward the similarity matching algorithm of multiple granularities time-series; finally, the experimental result proved that the algorithm can effectively reflect the time-series of multiple granularities.
