Patent ID: 7986848

Claim:
A method for a multi-resolution storage scheme for historical data, comprising: dividing, on a computer, historical data into a plurality of time frames; determining, on the computer, an amount of compression for each of the time frames, wherein at least two of the time frames have a different amount of compression; compressing, on the computer, a plurality of series of the historical data in multiple dimensions, wherein the amount of compression for each of the time frames is applied via a wavelet transform and output as wavelet coefficients resulting in multi-resolution historical data with older series of the historical data compressed as a two-dimensional image and younger series of the historical data compressed in a single dimension; storing the multi-resolution historical data; reconstructing, on the computer, the historical data through applying an inverse wavelet transform to the wavelet coefficients; calculating, on the computer, an error metric as a mean square error between the historical data and the reconstructed historical data; and outputting the error metric.
