Biased Boltzmann samplers and generation of extended linear languages with shuffle [PDF]
, 2012 This paper is devoted to the construction of Boltzmann samplers according to various distributions, and uses stochastic bias on the parameter of a Boltzmann sampler, to produce a sampler with a different distribution for the size of the output.

Hardware architecture for discrete stochastic arithmetic
, 2003 L'utilisation de l'arithmétique à virgule flottante dans le calcul scientifique pose des problèmes de précision. En effet, les nombres réels n'étant pas tous représentables en virgule flottante, certains vont devoir être approchés. L'arithmétique stochastique discrète permet d'estimer et de contrôler les arrondis de calcul.

Probabilistic arithmetic. I. Numerical methods for calculating convolutions and dependency bounds
, 1990 Probabilistic arithmetic involves the calculation of the distribution of arithmetic functions of random variables. This work on probabilistic arithmetic began as an investigation into the possibility of adapting existing numerical procedures (developed ...

Dynamical strategies using Discrete Stochastic Arithmetic for approximation methods
, 2006 Let us consider the converging sequence generated by successively dividing by two the step size used in an approximation method. With an appropriate stopping criterion, we show that in the last approximation obtained, the significant bits which are not affected by round-off errors are in common with the exact result, up to one.

Weak Stability of Centred Quadratic Stochastic Operators
, 2019 We consider the weak convergence of iterates of so-called centred quadratic stochastic operators. These iterations allow us to study the discrete time evolution of probability distributions of vector-valued traits in populations of inbreeding or ...

Does positive dependence between individual risks increase stop-loss premiums?. [PDF]
Actuaries intuitively feel that positive correlations between individual risks reveal a more dangerous situation compared to independence. The purpose of this short note is to formalize this natural idea.
