Copula conditional tail expectation for multivariate financial risks

open access: yesArab Journal of Mathematical Sciences, 2018
Our goal in this paper is to propose an alternative risk measure which takes into account the fluctuations of losses and possible correlations between random variables.

A Hoeffding-Azuma Type Inequality for Random Processes

open access: yesInternational Journal of Analysis and Applications, 2023
The subject of this paper is a Hoeffding-Azuma type estimation for the difference between an adapted random process and its conditional expectation given a related filtration.

Unbounded weighted conditional expectation operators [PDF]

open access: yes, 2015
In this note basic properties of unbounded weighted conditional expectation operators are investigated. A description of polar decomposition and quasinormality in this context are provided. Also, we study hyperexpan- sive weighted conditional expectation

A Novel Analytical Formula for the Discounted Moments of the ECIR Process and Interest Rate Swaps Pricing

open access: yesFractal and Fractional, 2022
This paper presents an explicit formula of conditional expectation for a product of polynomial functions and the discounted characteristic function based on the Cox–Ingersoll–Ross (CIR) process.

Dynamic shortfall constraints for optimal portfolios [PDF]

open access: yesSurveys in Mathematics and its Applications, 2010
We consider a portfolio problem when a Tail Conditional Expectation constraint is imposed. The financial market is composed of n risky assets driven by geometric Brownian motion and one risk-free asset.

Gauss process state-space model optimization algorithm with expectation maximization

open access: yesInternational Journal of Distributed Sensor Networks, 2019
A Gauss process state-space model trained in a laboratory cannot accurately simulate a nonlinear system in a non-laboratory environment. To solve this problem, a novel Gauss process state-space model optimization algorithm is proposed by combining the ...

Different Types of Conditional Expectation and the Lueders - von Neumann Quantum Measurement

open access: yes, 2010
In operator algebra theory, a conditional expectation is usually assumed to be a projection map onto a sub-algebra. In the paper, a further type of conditional expectation and an extension of the Lueders - von Neumann measurement to observables with ...

Smoothing the payoff for efficient computation of Basket option prices [PDF]

open access: yes, 2016
We consider the problem of pricing basket options in a multivariate Black Scholes or Variance Gamma model. From a numerical point of view, pricing such options corresponds to moderate and high dimensional numerical integration problems with non-smooth ...

An approach for metric space with a convex combination operation and applications

open access: yes, 2015
In this paper, we embed metric space endowed with a convex combination operation, named convex combination space, into a Banach space and the embedding preserves the structures of metric and convex combination.

Riemann-Theta Boltzmann Machine

open access: yes, 2020
A general Boltzmann machine with continuous visible and discrete integer valued hidden states is introduced. Under mild assumptions about the connection matrices, the probability density function of the visible units can be solved for analytically ...
