Abstract

Abstract: This paper introduces a novel switching method which can be used to combine two or more PPM models. The work derives from our earlier work on modeling English and text mining, and the approach takes advantage of both to help improve the compression performance significantly. The performance of the combination of models is at least as good as (and in many cases significantly better than) the best performed of the individual models.
