Claim One:
1. A method of compressing a stream of input data elements to produce an output data stream, the method comprising the steps of: (a) selecting at least one model, from a set of predetermined mathematical models, each mathematical model parameterizing a space with a set of model specific coordinates, the coordinates represented by a tuple of at least one coordinate values, and outputting for each selected model parameters comprising a map, from a tuple of coordinate values in the model space to an approximating set of data values for at least one subportion of the data elements, (b) determining, for at least one subportion of the data elements, a label indicating a selected model, and the values of a tuple of model coordinates which map to a tuple of data values which, according to some measure of merit, best approximate the subportion of the data elements, and (c) outputting at least the model coordinates as at least a portion of an output data stream.
