A New Efficient Expression for the Conditional Expectation of the Blind Adaptive Deconvolution Problem Valid for the Entire Range ofSignal-to-Noise Ratio [PDF]

open access: yesEntropy, 2019
In the literature, we can find several blind adaptive deconvolution algorithms based on closed-form approximated expressions for the conditional expectation (the expectation of the source input given the equalized or deconvolutional output), involving ...

On the worst conditional expectation

open access: yesJournal of Mathematical Analysis and Applications, 2003
The paper deals with the characterization of coherent risk measures, framing the analysis within a unitary system for defined risks. In this order of ideas, continuous coherent risk measures on \(L^p\) are studied, in particular the law invariant ones. Special attention is paid to the worst conditional expectations, since, under opportune hypotheses on

On Independence Neutrosophic Random Variables [PDF]

open access: yesNeutrosophic Sets and Systems, 2021
In this article we study independence neutrosophic random variables and conditioned expectation, we prove that conditional variance is equal to neutrosophic conditional variance.

Operational meanings of a generalized conditional expectation in quantum metrology [PDF]

open access: yesQuantum, 2023
A unifying formalism of generalized conditional expectations (GCEs) for quantum mechanics has recently emerged, but its physical implications regarding the retrodiction of a quantum observable remain controversial.

Conditional Tail Expectation and Premium Calculation under Asymmetric Loss

open access: yesAxioms, 2023
In this paper, we calculate premiums that are based on the Conditional Tail Expectation (CTE) and asymmetric loss functions to account for the risk of both underestimation and overestimation losses.

A simple closed-form formula for the conditional moments of the Ornstein-Uhlenbeck process [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2020
This paper derives a simple closed-form formula for the n th conditional moment of the Ornstein-Uhlenbeck (O-U) process, for any positive integer n. The system of recursive ordinary differential equations (ODEs) associated with the n th conditional ...

Further characterization based on conditional expectations: new and extended findings

open access: yesJournal of Taibah University for Science, 2023
On the basis of conditional expectation of a random variable function, we present few characterization findings in this study. For a given function g, [Formula: see text], we present necessary and sufficient conditions for characterization results in ...

Computation of Conditional Expectations with Guarantees

open access: yesJournal of Scientific Computing, 2023
AbstractTheoretically, the conditional expectation of a square-integrable random variable Y given a d-dimensional random vector X can be obtained by minimizing the mean squared distance between Y and f(X) over all Borel measurable functions $$f :\mathbb {R}^d \rightarrow \mathbb {R}$$ f :

Modeling the Conditional Dependence between Discrete and Continuous Random Variables with Applications in Insurance

open access: yesMathematics, 2020
We jointly model amount of expenditure for outpatient visits and number of outpatient visits by considering both dependence and simultaneity by proposing a bivariate structural model that describes both variables, specified in terms of their conditional ...
