Distributional data analysis via quantile functions and its application to modelling digital biomarkers of gait in Alzheimer's Disease
Rahul Ghosal, Vijay R. Varma, Dmitri Volfson +5
With the advent of continuous health monitoring with wearable devices, users now generate their unique streams of continuous data such as minute-level step counts or heartbeats. Su…
Loss-analysis via Attention-scale for Physiologic Time Series
Jiawei Yang, Jeffrey M. Hausdorff
Physiologic signals have properties across multiple spatial and temporal scales, which can be shown by the complexity-analysis of the coarse-grained physiologic signals by scaling…
Decaying of Phase Synchronization - A Physiological Tool
Avi Gozolchiani, Shay Moshel, Jeffrey M. Hausdorff +3
We describe the effects of the asymmetry of cycles and non-stationarity in time series on the phase synchronization method. We develop a modified method that overcomes these effect…
Levels of Complexity in Scale-Invariant Neural Signals
Plamen Ch. Ivanov, Jeffrey M. Hausdorff, S. Havlin +5
Many physical and physiological signals exhibit complex scale-invariant features characterized by scaling and long-range power-law correlations, suggesting a possibly common…
A Stochastic Model of Human Gait Dynamics
Yosef Ashkenazy, Jeffrey M. Hausdorff, Plamen Ch. Ivanov +2
We present a stochastic model of gait rhythm dynamics, based on transitions between different ``neural centers'', that reproduces distinctive statistical properties of normal human…
