The method relies on the spectral decomposition of a particular type of kernels constructed from observed data. The independent components are computed for a surprisingly small sub-sample of the data, and can be efficiently extended to a much larger set of new observations. We demonstrate our method performance for the empirical solution of inverse problems in electro-magnetic measurements of geological formations, and in Acoustics. This method suggests a general tool for solving empirically inverse problems.
