Estimation in Poisson Noise: Properties of the Conditional Mean Estimator [PDF]

open access: yesIEEE Transactions on Information Theory, 2019
This paper considers estimation of a random variable in Poisson noise with signal scaling coefficient and dark current as explicit parameters of the noise model.

Bayesian Prediction of the First Order Statistics from Frecht Distribution When Sample Size is a Random Variable (A Numerical Investigation) [PDF]

open access: yesThe Egyptian Statistical Journal, 2000
This paper considers Bayesian prediction of order statistics when the sample size of the future sample is a random variable. It has been shown (see Lingappaiah (1986)) that this situation arises in the field as Biology Agriculture and in Quality Control.

Strong averaging principle for slow-fast SPDEs with Poisson random measures

open access: yes, 2015
This work concerns the problem associated with an averaging principle for two-time-scales stochastic partial differential equations (SPDEs) driven by cylindrical Wiener processes and Poisson random measures.

A Random-Effects Log-Linear Model with Poisson Distributions

open access: yesRevstat Statistical Journal, 2003
In several applications data are grouped and there are within-group correlations. With continuous data, there are several available models that are often used; with counting data, the Poisson distribution is the natural choice. In this paper a mixed log-

POISSON APPROXIMATION FOR RANDOM SUMS OF GEOMETRIC RANDOM VARIABLES [PDF]

open access: yesInternational Journal of Pure and Apllied Mathematics, 2013
In this paper, we determine bounds with different Poisson mean for the total variation distance between the distribution of random sums of in- dependent geometric random variables and an appropriate Poisson distribution. Two examples have been given to illustrate the results obtained.

Poisson approximation for independent geometric random variables [PDF]

open access: yesInternational Mathematical Forum, 2007
The Stein-Chen method is used to derive two formulas of uniform and non-uniform bounds on Poisson approximation for a sum of n independent geometric random variables. Application of these formulas is illustrated with the Poisson approximation to the negative binomial distribution.

In-Scene Calibration of Poisson Noise Parameters for Phase Image Recovery

open access: yesIEEE Open Journal of Signal Processing
In sensor metrology, noise parameters governing the stochastic nature of photon detectors play critical role in characterizing the aleatoric uncertainty of computational imaging systems such as indirect time-of-flight cameras, structured light imaging ...

Weighted Naive Bayes Text Classification Algorithm Based on Poisson Distribution [PDF]

open access: yesJisuanji gongcheng, 2020
Naive Bayes(NB) algorithm is simple and efficient when applied to text classification,but it has a bottleneck in accuracy due to the intrinsic assumption that attribute independence and attribute importance are consistent.To solve this problem,this paper
