Estimation of multiple poisson means under entropy loss by Ming-Chung Yang Download PDF EPUB FB2

For estimatingp(⩾ 2) independent Poisson means, the paper considers a compromise between maximum likelihood and empirical Bayes estimators. Such compromise estimators enjoy both good componentwise as well as ensemble by: 1.

This paper characterizes admissible linear estimators of multiple Poisson parameters under entropy loss. Estimators dominating some of the standard estimators are given.

Ghosh and Yang () considered entropy loss for simultaneous estimation of p-independent Poisson means. Rukhin and Ananda () considered the estimation problem of unknown variance of a multivariate nor- mal vector under quadratic loss and entropy by: In probability theory and statistics, the Poisson distribution (French pronunciation: ; in English often rendered / ˈ p w ɑː s ɒ n /), named after French mathematician Siméon Denis Poisson, is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant mean rate Support: k, ∈, N, 0, {\displaystyle k\in.

In estimation problems where over-estimation is more serious than under-estimation, the entropy loss is more appropriate than SEL and SISEL functions.

Some authors have used the following asymmetric and convex loss function (8) L (h (θ), δ) = δ h (θ) − ln δ h (θ) − 1, which is known as Stein's loss, to estimate the parameter Cited by: In various science/engineering applications, such as independent component analysis, image analysis, genetic analysis, speech recognition, manifold learning, evaluation of the status of biological systems and time delay estimation it is useful to estimate the differential entropy of a system or process, given some observations.

The simplest and most common approach uses histogram-based. Abstract. Let X 1, θ, X n (n > p) be a random sample from multivariate normal distribution N p (μ, Σ), where μ ε R p and Σ is a positive definite matrix, both μ and Σ being unknown.

We consider the problem of estimating the precision matrix Σ − this paper it is shown that for the entropy loss, the best lower-triangular affine equivariant minimax estimator of Σ −1 is Cited by: 5.

The paper deals with estimating shift point which occurs in any sequences of independent observations x1, x2,xm, xm+1,xn of poisson and geometric distributions. This shift point occurs in the sequence when xm i. m life data are observed.

With known shift point 'm', the Bayes estimator on befor and after shift process means θ1 and θ2 are derived for symmetric and assymetric. context of Kullback-Leibler loss in [34]. Under some conditions the analysis in [35] yields a root-nconsistent estimate of the entropy when 1 d 3.

The authors point out that the case d= 2 is of practical interest in projection pursuit. II.3 Estimates of entropy based on sample-spacings.

The action of U α is to thin X and then to add an independent Poisson random variable to it. In Section 4, we use U α to establish the maximum entropy property of the Poisson.

Binomial and Poisson Distributions as Maximum Entropy Distributions Peter Harremoës Abstract— The binomial and the Poisson distributions are shown to be maximum entropy distributions of suitably defined sets. Poisson’s law is considered as a case of entropy maximization, and also convergence in in-formation divergence is established.

An estimation problem of the mean µ of an inverse Gaussian distribution IG(µ, C µ) with known coefficient of variation c is treated as a decision problem with entropy loss function. A class of Bayes estimators is constructed, and shown to include MRSE estimator as its closure.

Two important members of this class can easily be computed using continued fractions. The c-Loss Function: Balancing Total and Individual Risk in the Simultaneous Estimation of Poisson Means Emil Aas Stoltenberg THESIS for the degree of.

The information entropy, often just entropy, is a basic quantity in information theory associated to any random variable, which can be interpreted as the average level of "information", "surprise", or "uncertainty" inherent in the variable's possible concept of information entropy was introduced by Claude Shannon in his paper "A Mathematical Theory of Communication".

e.g. repeat the entropy estimation experiment many times and compute the average.

We have developed a molecular mean-field theory—fourth-order Poisson–Nernst–Planck–Bikerman theory—for modeling ionic and water flows in biological ion channels by treating ions and water molecules of any volume and shape with interstitial voids, polarization of water, and ion-ion and ion-water correlations.

{(Yi,ξi),Yi∈ Π} is the Poisson marked point process we will work with.Ψ can be seen as a random variable with values in N:= {ϕlocally finite counting measure on Rd× M}. An important property of this process is stationarity, meaning that TyΨ = Ψd for all y∈ Rd, where the translation operator T y is defined as Tyϕ(B× L):= ϕ(B+y× L) for any Borel set B× L⊂ Rd× M and ϕ∈ by: 3.

The Poisson distribution describes the number of occurrences of an event in a fixed interval, under the assumption that occurrences are independent. In particular, the constraint that the events should be independent means that not every discrete distribution is a valid candidate for describing this system, and motivates the choice of the union.

A novel loss function that penalizes bad estimates of each of the means and the sum of the means is introduced. Under this loss function, a class of.

Entropy is a concept that originated in thermodynamics, and later, via statistical mechanics, motivated entire branches of information theory, statistics, and machine learning. Maximum entropy is the state of a physical system at greatest disorder or a statistical model of least encoded information, these being important theoretical analogs.

Here, as usual, the entropy of a distribution p is defined as H(p) = p[ln(1=p)] and the relative entropy, or Kullback-Leibler divergence, as D(p k q) = p[ln(p=q)].

Thus, the maximum entropy principle. The Entropy of a Poisson Distribution Problem *, by C. ROBERT APPLEDORN (Indiana University). The following problem arose during a study of data compression schemes for digitally encoded radiographic images. Specifically, Huffman optimum (minimum) codes are employed to reduce the storage requirements for high resolution gray-levelCited by: In this case, the loss function is the negative log loss: loss(q;X) = logq(X).

The expected value of this loss function is the risk: Risk(q) = E p[log 1 q(x)]:We want to nd a distribution qthat minimizes the risk. However, notice that minimizing the risk with respect to a distribution qis exactly minimizing the relative entropy between pand q.

Maximum Likelihood and Entropy Cosma Shalizi posted recently about optimization for learning. This is a recurring theme in statistics 1: set up a functional combining empirical risk and a regularization term for smoothing, then use optimization to find a parameter value that minimizes this functional.

The most common estimators of MI are based on plug-in density estimation, e.g., using the histogram, kernel density or kNN density estimators [21,22]. Motivated by ensemble methods applied to divergence estimation [23,24], in an ensemble method for combining multiple KDE bandwidths was proposed for estimating MI.

Thus, all we can do is attempt to mitigate 4 the bias, but we can never hope to remove it completely.
