String Kernels for Native Language Identification: Insights from Behind the Curtains
Text mining classification task depend on the characteristics of high level language features language task identity string
2016/10/31
The most common approach in text mining classification tasks is to rely on features like words, part-of-speech tags, stems, or some other high-level linguistic features. Recently, an approach that use...
The availability of large scale data sets of manually annotated predicate-argument structures has recently favored the use of machine learning approaches to the design of automated semantic role label...
Measuring Volterra kernels
Volterra nonlinear system the kernel linear pseudo noise electroacoustic transducer
2015/8/13
Volterra series have been in the engineering literature for some time now, and yet there have been few attempts to measure Volterra kernels. This paper discusses techniques for measuring the Volterra ...
FAST DIRECTIONAL MULTILEVEL ALGORITHMS FOR OSCILLATORY KERNELS
N-body problems scattering problems Helmholtz equation oscillatory kernels fast multipole methods separated representations random sampling operator compression multidirectional computation multiscale methods
2015/7/14
This paper introduces a new directional multilevel algorithm for solving N-body orN-point problems with highly oscillatory kernels. These systems often result from the boundary integral formulations o...
The Leaf Projection Path View of Parse Trees:Exploring String Kernels for HPSG Parse Selection
The Leaf Projection Path View Parse Trees String Kernels HPSG Parse Selection
2015/6/12
We present a novel representation of parse trees as lists of paths (leaf projection paths) from leaves to the top level of the tree. This representation allows us to achieve significantly higher accur...
Correlation between Black Point Symptoms and Fungal Infestation and Seedling Viability of Wheat Kernels

The level of occurrence of black point, the spectrum of fungal species and damage to wheat seedling vigour
associated with it were assessed during 2003 and 2004 in the Slovak Republic. The incidence...

2015/3/1
The influence of agro-environmental factors (year, cultivar and climatic factors) on the occurrence of fungi on kernels of malt barley, species spectrum and seedling viability were evaluated during 20...
Shape-Based Image Matching Using Heat Kernels and Diffusion Maps
Image Matching Diffusion Maps Mathematical Morphology
2014/9/9
2D image matching problem is often stated as an image-to-shape or shape-to-shape matching problem. Such shape-based matching techniques should provide the matching of scene image fragments registered ...
Resummed memory kernels in generalized system-bath master equations
Langevin equation Perturbation theory Molecular dynamicsPopulation dynamics Matrix equations
2014/8/21
Generalized master equations provide a concise formalism for studying reduced population dynamics. Usually, these master equations require a perturbative expansion of the memory kernels governing the ...
Linear system identification using stable spline kernels and PLQ penalties
linear system identification bias-variance trade off kernel-based regularization robust statistics interior point methods piecewise linear quadratic densities
2013/4/27
The classical approach to linear system identification is given by parametric Prediction Error Methods (PEM). In this context, model complexity is often unknown so that a model order selection step is...
Effect of cooking methods on total phenolic and carotenoid amounts and DPPH radical scavenging activity of fresh and frozen sweet corn (Zea mays) kernels
Zea mays L. cooking process phenolics β-carotene antioxidan
2014/2/24
We evaluated the effect of three different cooking methods on antioxidant content and radical scavenging activity of sweet corn. Both fresh and frozen sweet corn kernels were boiled, microwaved, and s...
Let (V,A) be a weighted graph with a finite vertex set V,with a symmetric matrix of nonnegative weightsAand with Laplacian ∆. LetS∗: V ×V 7→ R be a symmetric kernel defined on the vertex s...
Semispectral Measures and Feller markov Kernels
Semispectral Measure Markov Kernel C-algebras Quantum Mechanics
2012/7/11
It is well known \cite{B1,P} that a real positive semispectral measure $F$ is commutative if and only if there exist a self-adjoint operator $A$ and a Markov kernel $\mu_{(\cdot)}(\cdot):\sigma(A)\tim...
Identifying High-Impact Sub-Structures for Convolution Kernels in Document-level Sentiment Classification
High-Impact Sub-Structures Convolution Kernels Document-level Sentiment Classification
2013/4/22
Convolution kernels support the modeling of complex syntactic information in machine-learning tasks. However, such models are highly sensitive to the type and size of syntac-tic structure used. It is ...

2012/4/23
Let $G$ be a simply-connected semisimple algebraic group scheme over an algebraically closed field of characteristic $p > 0$. Let $r \geq 1$ and set $q = p^r$. We show that if a rational $G$-module $M...
