Robust estimation of a Markov chain transition matrix from multiple sample paths

Statistica Neerlandica, Volume 80, Issue 1, February 2026.
Markov chains are fundamental models for stochastic dynamics, with applications in a wide range of areas such as population dynamics, queueing systems, reinforcement learning, and Monte Carlo methods. Estimating the transition matrix and stationary distribution from observed sample paths is a core statistical challenge, particularly when multiple ...

Distributed Task Encoding

, 2017
The rate region of the task-encoding problem for two correlated sources is characterized using a novel parametric family of dependence measures. The converse uses a new expression for the $\rho$-th moment of the list size, which is derived using the ...

Nearly Hamilton cycles in sublinear expanders and applications

Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract We develop novel methods for constructing nearly Hamilton cycles in sublinear expanders with good regularity properties, as well as new techniques for finding such expanders in general graphs. These methods are of independent interest due to their potential for various applications to embedding problems in sparse graphs.

Amplifying Inter-Message Distance: On Information Divergence Measures in Big Data

IEEE Access, 2017
Message identification (M-I) divergence is an important measure of the information distance between probability distributions, similar to Kullback-Leibler (K-L) and Renyi divergence. In fact, M-I divergence with a variable parameter can make an effect on

Mathematical Modeling of Amoxicillin Synthesis in Batch and Semi‐Batch Reactor: Application of Bayesian Statistics and Genetic Algorithm

Biotechnology and Bioengineering, Volume 123, Issue 1, Page 104-115, January 2026.
Synthesis of amoxicillin: The reaction catalyzed by penicillin G acylase is investigated in an enzymatic reactor, considering both Michaelis–Menten and mechanism‐based models with reaction and equilibrium constants. Parameters are estimated via MCMC and Genetic Algorithm, with MCMC showing superior performance in validating the mathematical model in a ...

Precision-Recall Curves Using Information Divergence Frontiers [PDF]

, 2003
Despite the tremendous progress in the estimation of generative models, the development of tools for diagnosing their failures and assessing their performance has advanced at a much slower pace. Recent developments have investigated metrics that quantify

Statistical Divergence and Paths Thereof to Socioeconomic Inequality and to Renewal Processes

Entropy
This paper establishes a general framework for measuring statistical divergence. Namely, with regard to a pair of random variables that share a common range of values: quantifying the distance of the statistical distribution of one random variable from ...

Ant Colony Optimization PID Control of Hypnosis With Propofol Using Renyi Permutation Entropy as Controlled Variable

IEEE Access, 2019
General anesthesia is a critical procedure in clinical surgery. To offer a closed control of depth of hypnosis, we establish a closed-loop anesthetic delivery system for propofol anesthesia.
