WebbPolynomial chaos (PC) has been used extensively recently to model uncertainty in physical applications. It originated from homogenous chaos first defined by Wiener as the span … Polynomial chaos (PC), also called polynomial chaos expansion (PCE) and Wiener chaos expansion, is a method for representing a random variable in terms of a polynomial function of other random variables. The polynomials are chosen to be orthogonal with respect to the joint probability distribution of … Visa mer Polynomial chaos expansion (PCE) provides a way to represent a random variable $${\displaystyle Y}$$ with finite variance (i.e., $${\displaystyle \operatorname {Var} (Y)<\infty }$$) as a function of an Visa mer In a non-intrusive setting, the estimation of the expansion coefficients $${\displaystyle c_{i}}$$ for a given set of basis functions Let Visa mer In many practical situations, only incomplete and inaccurate statistical knowledge on uncertain input parameters are available. Fortunately, to construct a finite-order … Visa mer Polynomial chaos can be utilized in the prediction of non-linear functionals of Gaussian stationary increment processes conditioned on their … Visa mer • Orthogonal polynomials • Surrogate model • Variance-based sensitivity analysis • Karhunen–Loève theorem • Hilbert space Visa mer

The requirements for a set function to be a probability measure on a probability space are that: • must return results in the unit interval returning for the empty set and for the entire space. • must satisfy the countable additivity property that for all countable collections of pairwise disjoint sets: μ ( ⋃ i ∈ N E i ) = ∑ i ∈ N μ ( E i ) . {\displays… WebbElectronic Journal of Probability We consider Gaussian multiplicative chaos measures defined in a general setting of metric measure spaces.

Webb1 maj 2016 · The Gaussian multiplicative chaos (GMC) is the natural generalization of such a random measure to the setting when the field ( X ( t)) is defined in a distributional sense rather than pointwise, i.e. via a family of formal “integrals” against test functions from an appropriate class.
