A duality view of spectral methods for dimensionality reduction
Duality spectrum the nonlinear dimension reduction locally linear embedding Laplacian sparse matrix
2015/8/10
We present a unified duality view of several recently emerged spectral methods for nonlinear dimensionality reduction, including Isomap, locally linear embedding, Laplacian eigenmaps, and maximum vari...
Identification of Stearoyl-CoA Desaturase (SCD) Gene Interactions in Korean Native Cattle Based on the Multifactor-dimensionality Reduction Method
Native Cattle Multifactor-Dimensionality Reduction (MDR) Single Nucleotide Polymorphism (SNP) Stearoyl-CoA Desaturase1 (SCD1) Gene
2016/5/12
Fat quality is determined by the composition of fatty acids. Genetic relationships between this composition and single nucleotide polymorphisms (SNPs) in the stearoyl-CoA desaturase1 (SCD1) gene were ...
urbulence damping as a measure of the flow dimensionality

The dimensionality of turbulence in uid layers determines their properties. We study electro-
magnetically driven ows in nite depth uid layers and show that eddy viscosity, which appears as a res...
The Curse of Dimensionality for Monotone and Convex Functions of Many Variables
Convex Functions Many Variables
2010/11/22
We study the integration and approximation problems for monotone and convex bounded functions that depend on $d$ variables, where $d$ can be arbitrarily large. We consider the worst case error for al...
Nonlinear dimensionality reduction in climate data
Nonlinear dimensionality reduction climate data
2009/11/11
Linear methods of dimensionality reduction are useful tools for handling and interpreting high dimensional data. However, the cumulative variance explained by each of the subspaces in which the data s...

2010/9/14
In this paper we will look at the connection of frames and finite dimensionality. The focus is to present simple algorithms, which are available online. We will give basic algorithms to use with frame...
Multifactor Dimensionality Reduction (MDR) Analysis to Detect Single Nucleotide Polymorphisms Associated with a Carcass Trait in a Hanwoo Population
Multifactor-dimensionality Reduction (MDR) SNP Hanwoo Association Study
2016/4/27
Studies to detect genes responsible for economic traits in farm animals have been performed using parametric linear models. A non-parametric, model-free approach using the ??expanded multifactor-dimen...
Holographic Algorithms: The Power of Dimensionality Resolved
Holographic Algorithms Dimensionality Resolved
2012/11/29
Valiant’s theory of holographic algorithms is a novel methodology to achieve exponential speed-ups in computation. A fundamental parameter in holographic algorithms is the dimension of the linear basi...
