Static hedging of Asian options under Lévy models: the comonotonicity approach. [PDF]
In this paper we present a simple static super-hedging strategy for the payoff of an arithmetic Asian option in terms of a portfolio of European options. Moreover, it is shown that the obtained hedge is optimal in some sense.

Numerical approximation of effective coefficients in stochastic homogenization of discrete elliptic equations [PDF]
We introduce and analyze a numerical strategy to approximate effective coefficients in stochastic homogenization of discrete elliptic equations. In particular, we consider the simplest case possible: An elliptic equation on the $d$-dimensional lattice $Z^

Leveraging Large Language Models for Agent‐Based Simulation of Human‐Water System Interactions
Abstract Modeling human–water system interactions is essential for understanding the co‐evolution of human society and hydrological extremes. Agent‐based models (ABMs) are widely used for this purpose, yet they face persistent challenges, including manually coded rules, simplified behavioral assumptions, and limited integration of qualitative ...

A Mixed Frequency BVAR for the Australian Economy*
A mixed frequency vector autoregression (MFVAR) model is proposed for nowcasting, forecasting and backcasting Australian macroeconomic indicators at monthly and quarterly frequencies. A novel augmented Minnesota prior for MFVAR models is also introduced.

New Heuristics for Stable LDA Parameter Search
ABSTRACT The Latent Dirichlet Allocation (LDA) algorithm automatically extracts latent topics from a textual corpus, but configuring its parameters can be difficult and time‐consuming. Optimization algorithms can help determine the best parameters, but not necessarily the optimal ones.

ABSTRACT Genomic selection (GS) is critical for accelerating genetic gain in modern plant breeding. Deep learning approaches offer powerful non‐linear representation capabilities for modelling non‐additive effects. However, their application in GS remains restricted, as high‐dimensional, low‐sample and noisy data hinder the identification of ...

Dynamic restarting strategy for a BICGSTAB algorithm using discrete stochastic arithmetic
Introduction A lot of scientic elds require a resolution of a linear equation system. It gives often rise to a very large sparse unsymmetric matrix. Sometimes, we can only access its elements implicitly that is to say we only know how to make operations

Some experiments on the evaluation of functional ranges using a random interval arithmetic
International audienceA software tool using standard and special interval arithmetic operations together with an idea which is developed in the discrete stochastic arithmetic (DSA) approach for round-off error evaluation is proposed in this paper for a ...
