A method for compressing an initial dataset may be implemented on a data processing system. The method may include generating a group of bootstrap samples of wavelet coefficients from the initial dataset using a wavelet basis function. An average quantile of the group of bootstrap samples of wavelet coefficients may be determined. The group of wavelet coefficients may be compressed by deleting initial wavelet coefficients having magnitudes less than the coefficient cutoff value equal to the average quantile. The compressed group of wavelet coefficients and the wavelet basis function may be used to approximate the initial dataset. |
