Robust PCFG-based generation using automatically acquired LFG approximations [PDF]
, 2006 We present a novel PCFG-based architecture for robust probabilistic generation based on wide-coverage LFG approximations (Cahill et al., 2004) automatically extracted from treebanks, maximising the probability of a tree given an f-structure. We evaluate

Robust Sequential Testing of Hypotheses on Discrete Probability Distributions
Austrian Journal of Statistics, 2016 The paper is devoted to analysis of approximations of the models in sequential hypotheses testing and to construction of new robust sequential test under the distortions presented by mixtures of probability distributions.

Nuclear interactions at volume reflection: Perturbative treatment
Physical Review Special Topics. Accelerators and Beams, 2012 Excess of nuclear interaction probability at volume reflection is evaluated within the approximation of dominance of the continuous planar potential and thin nuclear concentrations. The domain of the adopted approximations is determined.

A comparison of approximations to percentiles of the noncentral chi2-distribution
Revista de Matemática: TeorÃa y Aplicaciones, 2009 Various approximations to percentiles of the noncentral 2-distribution are examined for their accuracy over a wide range of values of the parameters of the distribution. Keywords: Probability distribution, percentiles, numerical approximation.

Approximating the Tail Probability of the t-Distribution: A Bayesian Approach
Sultan Qaboos University Journal for Science, 2001 A Bayesian technique is used to approximate the tail probability of the t-distribution. A set of upper and lower bounds are obtained for this probability. Based on their simplicity and accuracy, these bounds are very adequate to use.

An Approximation to the Probability Integral
The Annals of Mathematical Statistics, 1946 It is shown that $\frac{1}{\sqrt{2\pi}} \int_{-x}^x e^{-\frac{1}{2}t^2} dt \geq \lbrack 1 - e^{-(2/\pi)x^2}\rbrack^\frac{1}{2}$ and that the equality is never in error by as much as three-fourths of one percent. Other approximations are discussed.

Matrix Integral Approach to MIMO Mutual Information Statistics in High-SNR Regime
Entropy, 2019 In this work, an analytical framework for deriving the exact moments of multiple-input- multiple-output (MIMO) mutual information in the high-signal-to-noise ratio (SNR) regime is proposed.

A Novel Probability Model for Suppressing Multipath Ghosts in GPR and TWI Imaging: A Numerical Study
Leida xuebao, 2015 A novel concept for suppressing the problem of multipath ghosts in Ground Penetrating Radar (GPR) and Through-Wall Imaging (TWI) is presented. Ghosts (i.e., false targets) mainly arise from the use of the Born or single-scattering approximations that ...

Fusion probability of massive nuclei in reactions leading to heavy composite nuclear systems [PDF]
EPJ Web of Conferences, 2019 Reactions between massive nuclei show a considerable reduction in fusion-evaporation cross-sections at the Coulomb barrier according to the comparison of experimental values with those calculated by barrier passing (BP) and statistical model (SM ...
