Daydreaming algorithm for Biased Patterns
Mikiya Doi, Masayuki Ohzeki, Federico Ricci-Tersenghi
The \emph{Daydreaming} algorithm has been recently proposed in Ref.~\cite{Serricchio2025} as a learning rule that simultaneously reinforces stored patterns and suppresses spurious…
Existence of a Phase Transition in the One-Dimensional Ising Spin Glass Model with Long-Range Interactions on the Nishimori Line
Manaka Okuyama, Masayuki Ohzeki
Dyson [Commun. Math. Phys. 12, 91 (1969)] rigorously proved the existence of a phase transition in the one-dimensional Ising model with long-range interactions of the form …
Temperature chaos as a logical consequence of the reentrant transition in spin glasses
Hidetoshi Nishimori, Masayuki Ohzeki, Manaka Okuyama
Temperature chaos is a striking phenomenon in spin glasses, where even slight changes in temperature lead to a complete reconfiguration of the spin state. Another intriguing effect…
Typical reconstruction limit and phase transition of maximum entropy method
Masaru Hitomi, Masayuki Ohzeki
We investigate the dependence of the maximum entropy method (MEM) reconstruction performance on the default model. The maximum entropy method is a reconstruction technique that uti…
Optimization of Connection Patterns between Mobile Phones and Base Stations using Quantum Annealing
Taisei Takabayashi, Shoichi Sudo, Toshihiro Aoki +2
In current mobile networks, optimizing which base station a mobile phone in a particular area connects to is crucial for ensuring good communication quality for each mobile phone b…
Existence of long-range order in random-field Ising model on Dyson hierarchical lattice
Manaka Okuyama, Masayuki Ohzeki
We study the random-field Ising model on a Dyson hierarchical lattice, where the interactions decay in a power-law-like form, , with respect to the distance. Witho…
