Inferring Microscopic Explanatory Structures from Observational Constraints via Large Deviations
Akihisa Ichiki
We study how macroscopic observational constraints restrict admissible microscopic explanatory structures when no intrinsic order or dynamics is assumed a priori. Starting from an…
Relativity of Observation: Operational Intensive Variables in Nonequilibrium Thermodynamics
Akihisa Ichiki
We formulate nonequilibrium thermodynamics in which intensive variables acquire operational meaning through measurement protocols consistent with local reciprocity. Using physical…
A method for classification of data with uncertainty using hypothesis testing
Shoma Yokura, Akihisa Ichiki
Binary classification is a task that involves the classification of data into one of two distinct classes. It is widely utilized in various fields. However, conventional classifier…
Performance-guaranteed regularization in maximum likelihood method: Gauge symmetry in Kullback -- Leibler divergence
Akihisa Ichiki
The maximum likelihood method is the best-known method for estimating the probabilities behind the data. However, the conventional method obtains the probability model closest to t…
Stochastic dynamics without detailed balance condition connecting simple gradient method and Hamiltonian Monte Carlo
Akihisa Ichiki, Masayuki Ohzeki
Sampling occupies an important position in theories of various scientific fields, and Markov chain Monte Carlo (MCMC) provides the most common technique of sampling. In the progres…
Upper bound inequality for calculation time in simulated annealing analogous to adiabatic theorem in quantum systems
Akihisa Ichiki, Masayuki Ohzeki
It has been recently reported that classical systems have speed limit for state evolution, although such a concept of speed limit had been considered to be unique to quantum system…
