IEEE Access, 2018 Research on the uncertainty of wind power has a significant influence on power system planning and decision-making. This paper proposes a novel method for wind power interval forecasting based on rough sets theory, weighted Markov chain, and kernel ...

Regularity of harmonic functions for some Markov chains with unbounded range [PDF]
arXiv, 2012 We consider a class of continuous time Markov chains on $\Z^d$. These chains are the discrete space analogue of Markov processes with jumps. Under some conditions, we show that harmonic functions associated with these Markov chains are H\"{o}lder continuous.

Markov chains with replacement
Advances in Applied Probability, 1974 Abstract The following modification of a general state space discrete-time Markov chain is considered: certain transitions are supposed “forbidden” and the chain evolves until there is such a transition. At this instant the value of the chain is “replaced” according to a given rule, and, starting from the new value, the chain evolves normally until ...

Generative Inverse Design of Metamaterials with Functional Responses by Interpretable Learning
Advanced Intelligent Systems, EarlyView.This work introduces random‐forest‐based interpretable generative inverse design (RIGID), a new single‐shot inverse design method for metamaterials using interpretable machine learning and Markov chain Monte Carlo sampling. Once trained on a small dataset, RIGID can estimate the likelihood of designs achieving target behaviors (e.g., wave‐based ...

A Hopf-power Markov chain on compositions [PDF]
Discrete Mathematics & Theoretical Computer Science, 2013 In a recent paper, Diaconis, Ram and I constructed Markov chains using the coproduct-then-product map of a combinatorial Hopf algebra. We presented an algorithm for diagonalising a large class of these "Hopf-power chains", including the Gilbert-Shannon ...

Metastable Markov chains [PDF]
arXiv, 2018 We review recent results on the metastable behavior of continuous-time Markov chains derived through the characterization of Markov chains as unique solutions of martingale problems.

arXiv, 2022 Rowmotion is a certain well-studied bijective operator on the distributive lattice $J(P)$ of order ideals of a finite poset $P$. We introduce the rowmotion Markov chain ${\bf M}_{J(P)}$ by assigning a probability $p_x$ to each $x\in P$ and using these probabilities to insert randomness into the original definition of rowmotion.

Phosphatemia is an Independent Prognostic Factor in Amyotrophic Lateral Sclerosis
Annals of Neurology, EarlyView.Objective The objective of this study was to evaluate the prognostic value of several muscle damage biomarkers. Methods Data from Piemonte and Valle d'Aosta Amyotrophic Lateral Sclerosis (PARALS) were considered for this study. Survival was defined as the time from diagnosis to death, tracheostomy, or the censoring date.

A Markov chain on the symmetric group which is Schubert positive? [PDF]
arXiv, 2011 We study a multivariate Markov chain on the symmetric group with remarkable enumerative properties. We conjecture that the stationary distribution of this Markov chain can be expressed in terms of positive sums of Schubert polynomials. This Markov chain is a multivariate generalization of a Markov chain introduced by the first author in the study of ...

Sloppiness Consistency in Biomechanical Models and Its Inspired Dual‐Space Model Optimization
Advanced Physics Research, EarlyView.This study addresses the challenge of balancing complexity, accuracy, and parameter identifiability in soft tissue constitutive modeling. By leveraging information geometry and sensitivity analysis, the sloppiness inherent in biomechanical models is revealed, and a model reduction framework is proposed. This approach optimizes parameter identifiability
