Data compression - Wikipedia, the free encyclopedia |
 | | Some compression algorithms exploit this property in order to encrypt data during the compression process so that decompression can only be achieved by an authorized party (eg. |
| | The very best compressors use probabilistic models whose predictions are coupled to an algorithm called arithmetic coding. |
| | Arithmetic coding, invented by Jorma Rissanen, and turned into a practical method by Witten, Neal, and Cleary, achieves superior compression to the better-known Huffman algorithm, and lends itself especially well to adaptive data compression tasks where the predictions are strongly context-dependent. |
