1. A method for lossless compression of data, said method comprising the steps of applying at least two different context based algorithm models for creating prediction pattern of the input data;

  • applying a neural network trained by back propagation to assign pattern probabilities when given the context as input;

    selecting the proper algorithm/predication for compression for each part of the data;

    applying the proper algorithm on the input data.
