集合压缩和统计建模

Integer Set Compression and Statistical Modeling

N. Jesper Larsson

摘要:

对于元素遵循均匀概率分布的设置,已经广泛地研究了整数集合和序列的压缩。此外,存在利用元素的聚类以实现更高压缩性能的方法。在这项工作中,我们解决的情况下,枚举的元素可能是任意的或随机的,但统计保持,以估计元素的概率。我们提出了一个递归的子集大小编码方法,能够受益于统计,探索置换的枚举顺序的元素概率的基础上的影响,并讨论这类压缩问题的一般属性和可能性。

英文摘要:

Compression of integer sets and sequences has been extensively studied for settings where elements follow a uniform probability distribution. In addition, methods exist that exploit clustering of elements in order to achieve higher compression performance. In this work, we address the case where enumeration of elements may be arbitrary or random, but where statistics is kept in order to estimate probabilities of elements. We present a recursive subset-size encoding method that is able to benefit from statistics, explore the effects of permuting the enumeration order based on element probabilities, and discuss general properties and possibilities for this class of compression problem.
