A Phase Description of Mutually Coupled Chaotic Oscillators
Haruma Furukawa, Takashi Imai, Toshio Aoyagi
The synchronization of rhythms is ubiquitous in both natural and engineered systems, and the demand for data-driven analysis is growing. When rhythms arise from limit cycles, phase…
Time Series Clustering with an EM algorithm for Mixtures of Linear Gaussian State Space Models
Ryohei Umatani, Takashi Imai, Kaoru Kawamoto +1
In this paper, we consider the task of clustering a set of individual time series while modeling each cluster, that is, model-based time series clustering. The task requires a para…
Phase description of chaotic oscillators
Takashi Imai, Hiromichi Suetani, Toshio Aoyagi
This paper presents a phase description of chaotic dynamics for the study of chaotic phase synchronization. A prominent feature of the proposed description is that it systematicall…
