Performance evaluation of coherent Ising machines against classical neural networks
Yoshitaka Haribara, Hitoshi Ishikawa, Shoko Utsunomiya +2
The coherent Ising machine is expected to find a near-optimal solution in various combinatorial optimization problems, which has been experimentally confirmed with optical parametr…
A Quantum Model for Coherent Ising Machines: Discrete-time Measurement Feedback Formulation
Atsushi Yamamura, Kazuyuki Aihara, Yoshihisa Yamamoto
Recently, the coherent Ising machine (CIM) as a degenerate optical parametric oscillator (DOPO) network has been researched to solve Ising combinatorial optimization problems. We f…
A Quantum Model for Coherent Ising Machine: Stochastic Differential Equations with Replicator Dynamics
Taime Shoji, Kazuyuki Aihara, Yoshihisa Yamamoto
The quantum theory of coherent Ising machines, based on degenerate optical parametric oscillators and measurement-feedback circuits, is developed using the positive repres…
Partially unstable attractors in networks of forced integrate-and-fire oscillators
Hai-Lin Zou, Zi-Chen Deng, Wei-Peng Hu +2
The asymptotic attractors of a nonlinear dynamical system play a key role in the long-term physically observable behaviors of the system. The study of attractors and the search for…
Hawkes process model with a time-dependent background rate and its application to high-frequency financial data
Takahiro Omi, Yoshito Hirata, Kazuyuki Aihara
A Hawkes process model with a time-varying background rate is developed for analyzing the high-frequency financial data. In our model, the logarithm of the background rate is model…
