Analysis framework for higher-order temporal correlations with applications to human heartbeats
Tibebe Birhanu, Hang-Hyun Jo
We propose a time series analysis framework focused on higher-order temporal correlations in the event sequence beyond the interevent time distribution by employing the burst-tree…
Noise-Activated Dopant Dynamics in Two-Dimensional Thermal Landscapes with Localized Cold Spots
Mesfin Taye, Yoseph Abebe, Tibebe Birhanu +2
Controlling dopant transport with high spatial precision is crucial for improving the semiconductor functionality, reliability, and scalability. Although prior models of noise-assi…
Maximum likelihood estimation of burst-merging kernels for bursty time series
Tibebe Birhanu, Hang-Hyun Jo
Various time series in natural and social processes have been found to be bursty. Events in the time series rapidly occur within short time periods, forming bursts, which are alter…
Burst-tree structure and higher-order temporal correlations
Tibebe Birhanu, Hang-Hyun Jo
Understanding characteristics of temporal correlations in time series is crucial for developing accurate models in natural and social sciences. The burst-tree decomposition method…
