The Stochastic Processes Generation in OpenModelica [PDF]

open access: yes, 2016
Background: Component-based modeling language Modelica (OpenModelica is open source implementation) is used for the numerical simulation of complex processes of different nature represented by ODE system. However, in OpenModelica standard library there is no routines for pseudo-random numbers generation, which makes it impossible to use for stochastic ...

Conditional generative models for learning stochastic processes

open access: yesQuantum Machine Intelligence, 2023
A framework to learn a multi-modal distribution is proposed, denoted as the Conditional Quantum Generative Adversarial Network (C-qGAN). The neural network structure is strictly within a quantum circuit and, as a consequence, is shown to represent a more efficient state preparation procedure than current methods.

A New Stochastic Process with Long-Range Dependence

open access: yesJournal of Statistical Theory and Applications (JSTA), 2020
In this paper, we introduce a fractional Generalized Hyperbolic process, a new stochastic process with long-range dependence obtained by subordinating fractional Brownian motion to a fractional Generalized Inverse Gaussian process.

A posteriori error estimation for stochastic static problems [PDF]

open access: yes, 2014
To solve stochastic static field problems, a discretization by the Finite Element Method can be used. A system of equations is obtained with the unknowns (scalar potential at nodes for example) being random variables. To solve this stochastic system, the
