Higher-Order Quantum Reservoir Computing
Quoc Hoan Tran, Kohei Nakajima
Quantum reservoir computing (QRC) is an emerging paradigm for harnessing the natural dynamics of quantum systems as computational resources that can be used for temporal machine le…
Evaluating the phase dynamics of coupled oscillators via time-variant topological features
Kazuha Itabashi, Quoc Hoan Tran, Yoshihiko Hasegawa
By characterizing the phase dynamics in coupled oscillators, we gain insights into the fundamental phenomena of complex systems. The collective dynamics in oscillatory systems are…
Scale-variant topological information for characterizing the structure of complex networks
Quoc Hoan Tran, Van Tuan Vo, Yoshihiko Hasegawa
The structure of real-world networks is usually difficult to characterize owing to the variation of topological scales, the nondyadic complex interactions, and the fluctuations in…
Topological time-series analysis with delay-variant embedding
Quoc Hoan Tran, Yoshihiko Hasegawa
Identifying the qualitative changes in time-series data provides insights into the dynamics associated with such data. Such qualitative changes can be detected through topological…
