Patent ID: 8738563

Claim:
A method comprising: obtaining a first data series and a second data series, wherein the first data series being associated with values of a parameter sampled from a first system, wherein the second data series being associated with values of the parameter sampled from a second system; calculating a correlation level between the first and second data series; in response to the correlation level being below a predetermined threshold, processing the first and second data series by: repeatedly selecting a transformation from a transformation repository, applying the transformation to the second data series, and computing the correlation level of the first data series and the transformed second data series; selecting, based on the computed correlation levels, the transformation of the plurality of transformations that yields a correlation level above the predetermined threshold; and providing a recommendation of a modification to the second system based on the selected transformation; wherein the plurality of transformations are associated with an order, and wherein said selecting the transformation from the plurality of transformations is performed based on the order, and reordering the transformations in the transformation repository to reduce computational intensity of the repeated applications; wherein at least one of said calculating, said applying and said providing is performed by a processor.
