Active Learning Strategy for Surrogate-Based Quantile Estimation of Field Function

open access: yesApplied Sciences, 2022
Uncertainty quantification is widely used in engineering domains to provide confidence measures on complex systems. It often requires to accurately estimate extreme statistics on computationally intensive black-box models.

A Fractional Order Recovery SIR Model from a Stochastic Process [PDF]

open access: yesBulletin of Mathematical Biology, 2015
Over the past several decades, there has been a proliferation of epidemiological models with ordinary derivatives replaced by fractional derivatives in an ad hoc manner.

Tensor-network approaches to counting statistics for the current in a boundary-driven diffusive system

open access: yesNew Journal of Physics, 2022
We apply tensor networks to counting statistics for the stochastic particle transport in an out-of-equilibrium diffusive system. This system is composed of a one-dimensional channel in contact with two particle reservoirs at the ends.

Markov processes of cubic stochastic matrices: Quadratic stochastic processes

open access: yesLinear Algebra and its Applications, 2019
We consider Markov processes of cubic stochastic (in a fixed sense) matrices which are also called quadratic stochastic process (QSPs). A QSP is a particular case of a continuous-time dynamical system whose states are stochastic cubic matrices satisfying an analogue of the Kolmogorov-Chapman equation (KCE).

Characterization of Predictive Behavior of a Retina by Mutual Information

open access: yesFrontiers in Computational Neuroscience, 2017
Probing a bullfrog retina with spatially uniform light pulses of correlated stochastic intervals, we calculate the mutual information between the spiking output at the ganglion cells measured with multi-electrode array (MEA) and the interval of the ...

Spurious OLS Estimators of Detrending Method by Adding a Linear Trend in Difference-Stationary Processes—A Mathematical Proof and Its Verification by Simulation

open access: yesMathematics, 2020
Adding a linear trend in regressions is a frequent detrending method in economic literatures. The traditional literatures pointed out that if the variable considered is a difference-stationary process, then it will artificially create pseudo-periodicity ...

Optimization of Energy-saving Operation Strategy of Heat Pump Hot-water System Using Stochastic Load Prediction

open access: yesZhileng xuebao, 2023
Reasonable optimization of the operation strategy is essential for saving energy in the long-term operation of heat pump systems. However, the strategy optimization process is susceptible to load uncertainty, which causes the optimized strategy to save ...

Runoff as a Stochastic Process

open access: yesInternational Journal of Mathematics and Computers in Simulation, 2022
Runoff stationary critical flow is investigated as a stochastic process by means of two routing simulation models, a stream confluence, which has beens interpreted as a Marcus- Lushnikov coalescence process, and a channel splitting model, which has ben interpreted as a Markov chain over a regular tree.

Stochastic resetting and applications [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2019
In this topical review we consider stochastic processes under resetting, which have attracted a lot of attention in recent years. We begin with the simple example of a diffusive particle whose position is reset randomly in time with a constant rate r ...
