Data compression method combining properties of PPM and CTW

Takumi Okazaki Kunihiko Sadakane Hiroshi Imai

pp. 268-283

Abstrakt

Universal compression and leaning has been interacting with each other. This paper combines two compression schemes, PPM (Prediction by Partial Match) and CTW (Context Tree Weighting), to a scheme which can predict the multi-alphabet probabilities to attain better compression ratio.
