Abstract(in English) | Compression by substring enumeration (CSE) is a lossless universal coding algorithm.Experimental results show that the compression performance of the CSE with a binary alphabet is almost the same as that of a popular data compression application while that of the CSE with a finite alphabet is worse. To improve the compression performance, we improve the lower bound of an inequality which plays a key role for compression performance in the CSE with a finite alphabet. Experimental results showed that the proposed CSE based on the improved inequality has almost the same performance of the CSE with a binary alphabet. |
