Abstract
Computer-supported methods and systems are disclosed for determining a characteristic function from a matrix that contains a defined number of data records having classifiable features. Processing of the matrix may first be performed by executing, for example, process steps for enrichment and compression. The matrix may be enriched by classes for the features. Further, the matrix may be compressed with a reduction in the number of data records. Finally, calculation of the characteristic functions may be performed by taking into account most of the data records of the matrix thus processed.
Claims44
A method for data processing with a program-controlled processor for determining a characteristic function from a matrix with a defined number of data records having classifiable features, the method comprising:
- processing the matrix in two processing modes, including an enrichment of the matrix with classes for the features, whereby the number of data records is preserved, and a compression corresponding to the classes with a reduction in the number of data records;
- and
- calculating the characteristic function based on the plurality of data records of the matrix thus processed.
A computer program product with computer-readable instructions for causing a processor, to perform a method for determining a characteristic function from a matrix with a defined number of data records having classifiable features, method comprising:
- processing the matrix in two processing modes, including enrichment of the matrix with classes for the features, whereby the number of data records is maintained, and compression corresponding to the classes, with a reduction in the number of data records (DS);
- and
- instructions for calculating the characteristic function, taking into account most of the data records of the matrix thus processed.
