Fast free-energy estimation for complex systems with nonreversible simulated tempering
Yoshihiko Nishikawa, Koji Hukushima
We discuss free-energy estimation for complex systems using simulated tempering with Wang--Landau-type feedback. We show that introducing nonreversible dynamics in temperature spac…
Proof of avoidability of the quantum first-order transition in transverse magnetization in quantum annealing of finite-dimensional spin glasses
Mizuki Sanatani, Naoto Shiraishi, Koji Hukushima
It is rigorously shown that an appropriate quantum annealing for any finite-dimensional spin system has no quantum first-order transition in transverse magnetization. This result c…
Effect of global shrinkage parameter of horseshoe prior in compressed sensing
Yasushi Nagano, Koji Hukushima
In sparse signal processing, this study investigates the effect of the global shrinkage parameter of a horseshoe prior, one of the global-local shrinkage prior, on the linear r…
Higher-order tensor renormalization group study of the - Ising model on a square lattice
Kota Yoshiyama, Koji Hukushima
Phase transitions of the - Ising model on a square lattice are studied using the higher-order tensor renormalization group(HOTRG) method. This system involves a competiti…
Phase transition in compressed sensing with horseshoe prior
Yasushi Nagano, Koji Hukushima
In Bayesian statistics, horseshoe prior has attracted increasing attention as an approach to the sparse estimation. The estimation accuracy of compressed sensing with the horseshoe…
Statistical-mechanical study of deep Boltzmann machine given weight parameters after training by singular value decomposition
Yuma Ichikawa, Koji Hukushima
Deep learning methods relying on multi-layered networks have been actively studied in a wide range of fields in recent years, and deep Boltzmann machines(DBMs) is one of them. In t…
