## Java implementation of arithmetic coding and PPM compression

Description

Arithmetic coding is a general technique for coding the outcome of a stochastic process based on an adaptive model. The expected bit rate is the cross-entropy rate of the model versus the actual process. PPM, prediction by partial matching, is an adaptive statistical model of a symbol sequence which models the likelihood of the next byte based on a (relatively short) suffix of the sequence of previous bytes.Upload more screenshots
