Abstract
The present invention provides a system and method for time-series with compression accuracy as a function of time. Briefly described, in architecture, one embodiment of the system, among others, can be implemented as follows. The system includes a computer with a processor. The system performs a method receiving a data set on the computer, utilizing a plurality of filter banks to transform the data set into a plurality coefficients, wherein each coefficient is associated with a basis function, and quantizing the plurality of coefficients, wherein the quantization maps the plurality of coefficients into certain value ranges. Then, system further performs determining a threshold based upon each coefficient effect on a time domain, disregarding the coefficient that fall below the threshold, and storing any remaining coefficients as compressed data for the data set.
