基于随机时间弯曲观测值的时间序列估计

Time-Series Estimation from Randomly Time-Warped Observations

İlker Bayram

摘要:

我们考虑的问题,估计一个信号从其扭曲的意见。这样的估计通常通过一些反向弯曲来改变观测值,或者求解计算要求高的优化公式来执行。虽然如果观测值很少,这些可能是不可避免的,但当大量扭曲观测值可用时,运行此类算法的成本可能过高。我们考虑的情况下,我们有很多的意见,并提出了一个计算简单的算法估计的功能感兴趣。我们证明了实用的算法上流式生物医学信号。

英文摘要:

We consider the problem of estimating a signal from its warped observations. Such estimation is commonly performed by altering the observations through some inverse-warping, or solving a computationally demanding optimization formulation. While these may be unavoidable if observations are few, when large amounts of warped observations are available, the cost of running such algorithms can be prohibitive. We consider the scenario where we have many observations, and propose a computationally simple algorithm for estimating the function of interest. We demonstrate the utility of the algorithm on streaming biomedical signals.
