一种通用的双效率无损数据压缩四维模型

A Universal 4D Model for Double-Efficient Lossless Data Compressions

Philip B. Alipour

摘要:

本文讨论了一种用于8位字符的无损数据压缩和解压缩的组合模糊二进制与或(FBAR)算法的理论、模型、实现和性能。一个组合的成对标志被用作新的零/非零,不纯/纯位对运算符,其中它们的组合形成一个4D超立方体来压缩字节序列。压缩后的序列存储在一个固定大小的网格文件中。解压缩是通过在I/O数据转换期间使用固定大小的转换表(TT)来访问网格文件。与其他LDC算法相比,双效率(DE)熵表示50%的压缩与合理的比特率进行了观察。在代码中双重扩展TT组件的使用,通过其对LDCs > 87.5%压缩的熵的负增长表现出普适可预测性,对于扩展数据库和网络通信非常重要。该算法在加密、二进制、模糊和概率等信息论方法上都是新颖的。因此,信息理论家,计算机科学家和工程师可能会发现该算法对其逻辑和应用有用。

英文摘要:

This article discusses the theory, model, implementation and performance of a combinatorial fuzzy-binary and-or (FBAR) algorithm for lossless data compression (LDC) and decompression (LDD) on 8-bit characters. A combinatorial pairwise flags is utilized as new zero/nonzero, impure/pure bit-pair operators, where their combination forms a 4D hypercube to compress a sequence of bytes. The compressed sequence is stored in a grid file of constant size. Decompression is by using a fixed size translation table (TT) to access the grid file during I/O data conversions. Compared to other LDC algorithms, double-efficient (DE) entropies denoting 50% compressions with reasonable bitrates were observed. Double-extending the usage of the TT component in code, exhibits a Universal Predictability via its negative growth of entropy for LDCs > 87.5% compression, quite significant for scaling databases and network communications. This algorithm is novel in encryption, binary, fuzzy and information-theoretic methods such as probability. Therefore, information theorists, computer scientists and engineers may find the algorithm useful for its logic and applications.
