摘要：
The present invention provides efficient window partitioning algorithms for entropy-encoding. The present invention enhances compression performance of entropy encoding based on the approach of modeling a dataset with the frequencies of its n-grams. The present invention may then employ approximation algorithms to compute good partitions in time O(s*log s) and O(s) respectively, for any data segment S with length s.
