We define an extended Bloch group for an arbitrary field F, and
show that this group is naturally isomorphic to Kind

2015/7/30
The discrimination technique for estimating the parameters of Gaussian mixtures that is based on the Extended Baum transformations (EB) has had significant impact on the speech recognition community. ...
Generalization of Extended Baum-Welch Parameter Estimation for Discriminative Training and Decoding
Extended Baum-Welch optimization speech
2015/7/28
We demonstrate the generalizability of the Extended Baum-Welch (EBW) algorithm not only for HMM parameter estimation but for decoding as well. We show that there can exist a general function associate...
Curvelets and Wave Atoms for Mirror-Extended Images
Curvelets Wave Atoms Mirror-Extended Images
2015/7/15
We present variants of both the digital curvelet transform, and the digital wave atom transform, which handle the image boundaries by mirror extension. Previous versions of these transforms treated im...
Extended Central Composite Designs and Their Statistical Properties
Statistical Properties Composite Designs
2015/3/18
There are several desirable properties that response surface designs may have. Sometimes we need designs which have more than
one desirable property at the same time. In this paper, we have proposed ...
An Extended Multistep Shanks Transformation and Convergence Acceleration Algorithm With Their Convergence and Stability Analysis

2012/8/10
The molecule solution of an extended discrete Lotka-Volterra equation is constructed,
from which a new sequence transformation is proposed. A convergence acceleration algorithm for
implementing this...

2014/6/3
Two hypergeometric terms f(k) and g(k) are said to be similar if the ratio f(k) =g(k) is a rational function of k. For similar hypergeometric terms f1(k),..., fm(k), we present an algorithm, called th...

He’s Variational Iteration Method Shallow Water Wave Equation
2013/1/30
In this paper, we consider two extended model equations for shallow water waves. We use He’s variational iteration method (VIM) to solve them. It is proved that this method is a very good tool for sha...
Natural frequencies of cracked functionally graded material plates by the extended finite element method
Mindlin plate theory vibration partition of unity methods extended finite element method
2011/9/15
Abstract: In this paper, the linear free flexural vibration of cracked functionally graded material plates is studied using the extended finite element method. A 4-noded quadrilateral plate bending el...
Extended BIC for linear regression models with diverging number of relevant features and high or ultra-high feature spaces
Diverging number of parameters Feature selection Extended Bayes information criterion High dimensional feature space
2011/9/5
Abstract: In many conventional scientific investigations with high or ultra-high dimensional feature spaces, the relevant features, though sparse, are large in number compared with classical statistic...

2011/8/24
Abstract: In [16], under mild conditions, a Wiener-Hopf type factorization is derived for the exponential functional of proper L\'evy processes. In this paper, we extend this factorization by relaxing...
Abstract: The extension complexity of a polytope $P$ is the smallest integer $k$ such that $P$ is the projection of a polytope $Q$ with $k$ facets. We study the extension complexity of $n$-gons in the...
