信号加噪声模型中的贪婪自适应压缩

Greedy Adaptive Compression in Signal-Plus-Noise Models

Entao Liu, Edwin K. P. Chong, Louis L. Scharf

摘要:

本文的目的是研究贪婪的自适应测量政策的上下文中的线性高斯测量模型的优化标准的基础上的信息增益。在连续标量测量的特殊情况下,我们提供了充分的条件下,贪婪的政策实际上是最佳的意义上最大化的净信息增益。在一般情况下,我们还讨论了贪婪策略不是最优的情况。

英文摘要:

The purpose of this article is to examine the greedy adaptive measurement policy in the context of a linear Guassian measurement model with an optimization criterion based on information gain. In the special case of sequential scalar measurements, we provide sufficient conditions under which the greedy policy actually is optimal in the sense of maximizing the net information gain. In the general setting, we also discuss cases where the greedy policy is not optimal.
