Warped infinitely divisible cascades: beyond power laws
نویسندگان
چکیده
We address the definitions and synthesis of stochastic processes which possess warped scaling laws that depart from power law behaviors in a controlled manner. We define warped infinitely divisible cascading (IDC) noise, motion and random walk. We provide a theoretical derivation of the scaling behavior of the moments of their increments. We provide numerical simulations of a warped log-Normal cascade to illustrate these results. Algorithms for synthesis and Matlab functions are available from our web pages.

Compound Poisson Cascades
Multiplicative processes and multifractals proved useful in various applications ranging from hydrodynamic turbulence to computer network traffic. Placing multifractal analysis in the more general framework of infinitely divisible laws, we design processes which possess at the same time stationary increments as well as multifractal and more general infinitely divisible scaling over a continuous...
متن کاملStochastic equations generating continuous multiplicative cascades
Discrete multiplicative turbulent cascades are described using a formalism involving infinitely divisible random measures. This permits to consider the continuous limit of a cascade developed on a continuum of scales, and to provide the stochastic equations defining such processes, involving infinitely divisible stochastic integrals. Causal evolution laws are also given. This gives the first ge...
متن کاملAppendix of Infinitely divisible cascades to model the statistics of natural images
Let us recall some basics on infinitely divisible probability distributions or laws. We denote the set of strictly positive integers by N∗. Definition A distribution G is called infinitely divisible if for all n ∈ N∗ there exists a distribution Gn such that G equals the n-fold convolution of Gn with itself, denoted as (Gn) . In other words, the distribution of a random variable S is infinitely ...
متن کاملOn the Law of Free Subordinators
We study the freely infinitely divisible distributions that appear as the laws of free subordinators. This is the free analog of classically infinitely divisible distributions supported on [0,∞), called the free regular measures. We prove that the class of free regular measures is closed under the free multiplicative convolution, t boolean power for 0 ≤ t ≤ 1, t free multiplicative power for t ...
متن کاملInfinitely Divisible Shot-Noise: Cascades of Non-Compact Pulses
Recently, the concept of infinitely divisible scaling has attracted much interest. As models of this scaling behavior, Poisson products of Cylindrical Pulses and more general infinitely divisible cascades have been proposed. This paper develops path and scaling properties of Poisson products of arbitrary pulses with non-compact support such as multiplicative and exponential shot-noise processes...
