摘要:

我们考虑一类大人口的过滤问题,其中每个人都是由相同的隐马尔可夫模型(HMM)建模。本文主要研究离散状态空间和连续观测空间下的Hyndrome中的聚集推理问题。连续的观察结果以一种方式聚合,使得个体与测量结果无法区分。我们提出了一个聚合推理算法称为连续观察集体向前向后算法。它扩展了最近提出的集体前向-后向算法的聚集推理在连续观测的情况下,离散观测的HISTORY。通过数值实验说明了该算法的有效性。

英文摘要:

We consider a class of filtering problems for large populations where each individual is modeled by the same hidden Markov model (HMM). In this paper, we focus on aggregate inference problems in HMMs with discrete state space and continuous observation space. The continuous observations are aggregated in a way such that the individuals are indistinguishable from measurements. We propose an aggregate inference algorithm called continuous observation collective forward-backward algorithm. It extends the recently proposed collective forward-backward algorithm for aggregate inference in HMMs with discrete observations to the case of continuous observations. The efficacy of this algorithm is illustrated through several numerical experiments.
