A Modified Lempel–ziv Welch Source Coding Algorithm for Efficient Data Compression
نویسندگان
چکیده
Lempel–Ziv Welch (LZW) algorithm is a well-known powerful data compression algorithm created by Abraham Lempel, Jacob Ziv, and Terry Welch. The algorithm is designed to be fast to implement but is not usually optimal because it performs only limited analysis of the data. A modified LZW algorithm on source coding will be proposed in this paper to improve the compression efficiency of the existing algorithms. Such method is to be implemented with appropriate modifications that gives the best performance and satisfies the requirements of the applications.

Data Compression on Columnar-Database Using Hybrid Approach (Huffman and Lempel-Ziv Welch Algorithm)
Columnar Oriented Database is an enhance approach to service to service the needs of Business Intelligence. A Columnar Oriented Database Management system that stores content by columns rather than the row. This type of data differs from traditional database with regards to performance, storage requirements and easy to modification of the schema. One of the major advantage of column based datab...
متن کاملUniversal Variable-to-Fixed Length Codes Achieving Optimum Large Deviations Performance for Empirical Compression Ratio
This paper clari es two variable-toxed length codes which achieve optimum large deviations performance of empirical compression ratio. One is Lempel-Ziv code with xed number of phrases, and the other is an arithmetic code with xed codeword length. It is shown that Lempel-Ziv code is asymptotically optimum in the above sense, for the class of nite-alphabet and nite-state sources, and that the ar...
متن کاملOn Efficient Entropy Approximation via Lempel-Ziv Compression
We observe a classical data compression algorithm due to Lempel and Ziv, well-known to achieve asymptotically optimal compression on a wide family of sources (stationary and ergodic), to perform reasonably well even on short inputs, provided the source is memoryless. More precisely, given a discrete memoryless source with large alphabet and entropy bounded away from zero, and a source sequence ...
متن کاملUniversal Deep Neural Network Compression
Compression of deep neural networks (DNNs) for memoryand computation-efficient compact feature representations becomes a critical problem particularly for deployment of DNNs on resource-limited platforms. In this paper, we investigate lossy compression of DNNs by weight quantization and lossless source coding for memory-efficient inference. Whereas the previous work addressed non-universal scal...
متن کاملRedundancy estimates for the Lempel-Ziv algorithm of data compression
The problem of non-distorting compression (or coding) of sequences of symbols is considered. For sequences of asymptotically zero empirical entropy, a modi0cation of the Lempel–Ziv coding rule is o1ered whose coding cost is at most a 0nite number of times worse than the optimum. A combinatorial proof is o1ered for the well-known redundancy estimate of the Lempel–Ziv coding algorithm for sequenc...
