Alphabet Partitioning Techniques for Semi-Adaptive Huffman Coding of Large Alphabets Alphabet Partitioning Techniques for Semi-Adaptive Huffman Coding of Large Alphabets∗
Practical applications that employ entropy coding for large alphabets often partition the alphabet set into two or more layers and encode each symbol by using some suitable prefix coding for each layer. In this paper, we formulate the problem of finding an alphabet partitioning for the design of a two-layer semi-adaptive code as an optimization problem, and give a solution based on dynamic prog...
متن کاملPractical Length-limited Coding for Large Alphabets
The use of Huuman coding for economical representation of a stream of symbols drawn from a deened source alphabet is widely known. In this paper we consider the problems encountered when Huuman coding is applied to an alphabet containing millions of symbols. Conventional tree-based methods for generating the set of codewords require large amounts of main memory; and worse, the codewords generat...
متن کاملA Memory-Efficient Adaptive Huffman Coding Algorthm for Very Large Sets of Symbols
The problem of computing the minimum redundancy codes as we observe symbols one by one has received a lot of attention. However, existing algorithms implicitly assumes that either we have a small alphabet — quite typically 256 symbols — or that we have an arbitrary amount of memory at our disposal for the creation of the tree. In real life applications one may need to encode symbols coming from...
متن کاملA Modified Ternary Tree for Adaptive Huffman Encoding Data Structure
The relevance and importance of data compression has shown a growing trend from the past four decades and is expected to continue remaining the same in the coming time. This paper has provided an overview of popular adaptive data compression methods of general utility. It evaluated these existing algorithms with a newly proposed scheme – Ternary Tree algorithm, implemented with improvements to ...
متن کاملPattern Coding Meets Censoring: (almost) Adaptive Coding on Countable Alphabets
Adaptive coding faces the following problem: given a collection of source classes such that each class in the collection has non-trivial minimax redundancy rate, can we design a single code which is asymptotically minimax over each class in the collection? In particular, adaptive coding makes sense when there is no universal code on the union of classes in the collection. In this paper, we deal...
