Phase transition in a long-memory log-Gaussian Cox process
Masato Hisakado, Shintaro Mori
We study a stochastic point process with power-law temporal correlations driven by hidden variables. We show that a generalized Merton-type model under an exponential-tail asset as…
Ornstein-Uhlenbeck Process for Horse Race Betting: A Micro-Macro Analysis of Herding and Informed Bettors
Tomoya Sugawara, Shintaro Mori
We model the time evolution of single win odds in Japanese horse racing as a stochastic process, deriving an Ornstein--Uhlenbeck process by analyzing the probability dynamics of vo…
The Impact of Network Structure on Ant Colony Optimization
Taiyo Shimizu, Shintaro Mori
Ant Colony Optimization (ACO) is a swarm intelligence methodology utilized for solving optimization problems through information transmission mediated by pheromones. As ants sequen…
Structural Properties of the Asymmetric Barabási-Albert Model in the Lattice Limit
Kazuaki Nakayama, Masato Hisakado, Shintaro Mori
The Asymmetric BA model extends the Barabási-Albert scale-free network model by introducing a parameter . As varies, the model transitions through different network structur…
Annealing of Ant Colony Optimization in the infinite-range Ising model
Shintaro Mori, Taiyo Shimizu, Masato Hisakado +1
Ant colony optimization (ACO) leverages the parameter to modulate the decision function's sensitivity to pheromone levels, balancing the exploration of diverse solutions with t…
Information cascade on networks and phase transitions
Masato Hisakado, Kazuaki Nakayama, Shintaro Mori
Herein, we consider a voting model for information cascades on several types of networks -- a random graph, the Barabási-Albert(BA) model, and lattice networks -- by using one para…
