Uncertainty-Aware Sparse Identification of Dynamical Systems via Bayesian Model Averaging
Shuhei Kashiwamura, Yusuke Kato, Hiroshi Kori +1
In many problems of data-driven modeling for dynamical systems, the governing equations are not known a priori and must be selected phenomenologically from a large set of candidate…
Qualitatively distinct mechanisms of noise-induced escape in diffusively coupled bistable elements
Hidemasa Ishii, Hiroshi Kori
The analysis of noise-induced escape in populations of bistable elements is challenging, because nonlinearity, coupling, and noise all play essential roles. We show that the interp…
Bayesian estimation of coupling strength and heterogeneity in a coupled oscillator model from macroscopic quantities
Yusuke Kato, Shuhei Kashiwamura, Emiri Watanabe +2
Various macroscopic oscillations, such as the heartbeat and the flashing of fireflies, are created by synchronizing oscillatory units (oscillators). To elucidate the mechanism of s…
Uncovering influence of football players' behaviour on team performance in ball possession through dynamical modelling
Hidemasa Ishii, Yohei Takai, Yuichiro Marui +3
A quest for uncovering influence of behaviour on team performance involves understanding individual behaviour, interactions with others and environment, variations across groups, a…
Nonequilibrium thermodynamics of populations of weakly-coupled low-temperature-differential Stirling engines with synchronous and asynchronous transitions
Songhao Yin, Hiroshi Kori, Yuki Izumida
This study developed the theory of nonequilibrium thermodynamics for populations of low-temperature-differential (LTD) Stirling engines weakly-coupled in a general class of network…
Periodic forces combined with feedback induce quenching in a bistable oscillator
Yusuke Kato, Hiroshi Kori
The coexistence of an abnormal rhythm and a normal steady state is often observed in nature (e.g., epilepsy). Such a system is modeled as a bistable oscillator that possesses both…
