Quantization of Discrete Probability Distributions

Yuriy A. Reznik

摘要:

我们研究的离散概率分布的量化问题,产生的通用编码,以及其他应用。我们表明,在许多情况下,这个问题可以减少到单位单纯形的覆盖问题。这种设置产生精确的渐近特性的高速率制度。我们还描述了一个简单的和渐近最优的算法来解决这个问题。该算法的性能进行了研究,并与几个已知的解决方案。

英文摘要:

We study the problem of quantization of discrete probability distributions, arising in universal coding, as well as other applications. We show, that in many situations this problem can be reduced to the covering problem for the unit simplex. This setting yields precise asymptotic characterization in the high-rate regime. We also describe a simple and asymptotically optimal algorithm for solving this problem. Performance of this algorithm is studied and compared with several known solutions.
