On the Weakenesses of Correlation Measures used for Search Engines' Results (Unsupervised Comparison of Search Engine Rankings)
Search Engines Correlation Measures Search Engine Rankings
2011/7/19
The correlation of the result lists provided by search engines is fundamental and it has deep and multidisciplinary ramifications. Here, we present automatic and unsupervised methods to assess whether...
Comparison of SCIPUFF Plume Prediction with Particle Filter Assimilated Prediction for Dipole Pride 26 Data
Data Assimilation Particle Filter
2011/7/19
This paper presents the application of a particle filter for data assimilation in the context of puff-based dispersion models. Particle filters provide estimates of the higher moments, and are well su...
Relative Density-Ratio Estimation for Robust Distribution Comparison
Density ratio Pearson divergence Outlier detection
2011/7/6
Divergence estimators based on direct approximation of density-ratios without going through separate approximation of numerator and denominator densities have been successfully applied to machine lear...
The Comparison of Three Major Occupations for User Acceptance of Information Technology: Applying the UTAUT Model
Unified Theory of Acceptance and Use of Technology (UTAUT) Manufacturing Service Bank
2013/2/23
This study investigated whether the differences of gender, age, and occupation for m-learning showed significance on the utilization of the mobile devices and to figure out if the variation may influe...
A Risk Comparison of Ordinary Least Squares vs Ridge Regression
Ridge Regression dimensional subspace
2011/6/16
We compare the risk of ridge regression to a simple variant of ordinary least squares, in which
one simply projects the data onto a finite dimensional subspace (as specified by a Principal
Component...
A comparison principle for functions of a uniformly random subspace
A comparison principle for functions random subspace
2011/3/25
This note demonstrates that it is possible to bound the expectation of an arbitrary norm of a random matrix drawn from the Stiefel manifold in terms of the expected norm of a standard Gaussian matrix ...
In an interlaboratory key comparison, a data analysis procedure for this comparison was proposed and recommended by CIPM [1, 2, 3], therein the degrees of equivalence of measurement standards of the l...
Corporate Performance: Does Ownership Matter? A Comparison of Foreign- and Domestic-Owned Firms in Greece and Portugal
Manufacturing industry quantile regression multinational corporations profitability
2010/11/5
The paper investigates whether multinational corporations (MNCs) operating in
Portugal and Greece perform differently than domestic firms. Departures from normality

A Comparison of Methods for Computing Autocorrelation Time
Comparison Autocorrelation Time
2010/11/8
This paper describes four methods for estimating autocorrelation time and evaluates these methods with a test set of seven series. Fitting an autoregressive process appears to be the most accurate met...
Downscaling extremes: A comparison of extreme value distributions in point-source and gridded precipitation data
Primary projections of extreme events reanalysis
2010/10/19
There is substantial empirical and climatological evidence that precipitation extremes have become more extreme during the twentieth century, and that this trend is likely to continue as global warmi...
Comparison of GA Based Heuristic and GRASP Based Heuristic for Total Covering Problem
Genetic Algorithm GRASP Total Covering Problem Boolean Operators Care and Share Operator
2013/2/23
This paper discusses the comparison of two different heuristics for total covering problem. The total covering problem is a facility location problem in which the objective is to identify the minimum ...
Missing Data：A Comparison of Neural Network and Expectation Maximisation Techniques
Missing Data Neural Network Expectation Maximisation Techniques
2010/4/28
Two techniques have emerged from the recent literature as candidate solutions to the problem
of missing data imputation, and these are the Expectation Maximisation (EM) Algorithm and the
auto-associ...
Dynamic shape analysis and comparison of leaf growth
geodesics parallel–transport Riemannian im–/submersion shape analysis forest biometry leaf growth
2010/3/10
In the statistical analysis of shape a goal beyond the analysis of static
shapes lies in the quantification of ‘same’ deformation of different shapes.
Typically, shape spaces are modelled as Riemann...
